  • Racor Filter Any Trouble?

    Getting that time of yr. Put my boat away last fall with a problem, with a fuel issue. Carbed 350 votec motor river boat.Engine start run fine until start put on step than would lose power sometimes just die out, Once it would catch run all the way upstearm no problem ,after going though everything filters, pulled tank,new lines, carb, vent,pickup tube, ect.... i mean just everything from front to back. I by chance had cheap napa inline fiter i carry in the box, put it on, by passed the racor and Bingo, no more problems, Thats where we are at today,Also ordered new fuel pump, First outting i will pressure Ck the one that is on it.This has been nagging me all winter! This set up only has about 56hr,s on it No issue at all the first yr? If were to blow in the napa filter like theres nothing there, The racor has a lot of restance like trying to blow up a balloon, My old boat i had a napa screw on type water seperator, 25yrs not a issue one. Does anybody have some imput on these racors,I have heard they are the best,also heard that some had to run a high Vol. pump?? Any thoughts thanks.

    Was it a new racor? The reason I ask is that they are rated for a specific GPH. If you have a filter that cannot keep up for the demand of fuel, the engine could be being starved.

      The boat came with it, No issues the first yr. I changed it,the filter part.. with the same part No# it had on it. Also talked with dealer in town for these, And had asked about the flow rate, was assured it was proper??? Thought they, might have gotten bad batch, Also once it catches the boat will run WOT with no problem all way up to 4300 rpm. cruse at 3600 for 1hr travel time, Thats whats bugging me?? just don,t know what to think.. Thanks for the reply.

        Racor 660R-RAC-01

        Susitna

        I spent several years selling racor filters - you will not find a better product. There is almost always two main problems that's commonly done with those units.
        1. The customer buys a unit thats not rated for the max GPH of the unit they are trying to support.
        2. The other main problem is usually associated with the way the unit is
        piped in. Many times it's associated with a quick disconnect they have installed in the line or the tubing is not big enough IE 5/16 when it should be 3/6 ID hose. If you have installed a quick disconnect - try removing them on a temp basis for a test run.

        The unit you should have on that boat is a Racor 660R-Rac-01 unless it's
        an inboard and the filter is installed in the engine compartment - if installed in the engine compartment it MUST have a metal bowl on the filter & that would be a racor 660R-RAC-02
        Make sure when you attach the filter to not get the seal crossed up - this would allow the unit to suck air and not seal.

          they tend to plug quickly when they plug

          They work great until they start to plug up. Then they plug up very quickly to the point of restricting fuel flow enough to cause a problem. This is typical of how most liquid filters with very fine effective opening sizes plug. The quick plugging process is calling "blinding".

          I had one blind on me in less than a day. Went from working great the previous trip to the engine stalling due to fuel starvation on the next trip. Put in a new filter cartridge and it worked fine.

          Moral of the story for a small boat is to carry a spare filter cartridge on the boat and keep it sealed in its original shrink wrap until you are ready to use it.........

          Big fancy boats can have two separate filters plumbed in parallel so they can just switch over to the new one when fuel pressure drops to a chosen point as measured on a fuel pressure gauge.

          In water treatment we put a "roughing filter" in front of the "polishing filter" to extend the run life of the "polishing filter"..... I imagine a cheap roughing fuel filter could be used before the Racors to extend their useful life also.

            No quick disconnect or Tees... 3/8in. line, Mines inside with the motor, Metal bowl 9/16 brass drain plug on the bottem. 660R Rac 02. As stated before all ran perfect the first yr. Now than, how about the replacement element Part,no# RACS3228UL Would you happin to Know the Micron rating of this one. Or another partno# i could use that would be rated higher flow? Thanks Jeff

              I had 4 of them in the boat i changed tank lines all new, new fuel, still had trouble, I kept the old ones just to see, I also cut two in half to see if i could tell what was going on, They looked new inside no dirt at all.I had added some additive in the gas,Quit that in the end also in case it was breaking the filter down.No differance there either, It,s just when i changed to that $6.00 Napa barrel filter. The problem went away, three trips no issues. These where last trips moose hunting back to back, than the ice up and the end for the yr. Weak fuel pump?/ Just can,t run my boat without a water/ seperator. Got to get to bottem of this, I think this flow Micron thing has some point to it. I did change out filter first of the yr.Like always just never thought much of it.Of course i Cked the No#they were the same. I have a master list of everything i do, hrs gas how far and parts need to buy for each yr. Oil filters, Fuel filters, Plugs, Oil Ect.. I keep log just like if it where an airplane Thanks for the replys, Keep them coming, Jeff

                Wrong Replacment Installed

                SusintaAK

                If you have an S3328UL installed on a 660R head it's the WRONG element for that base. The S3328UL is a good filter - BUT it goes with the S320R
                head. This one is about 4 inches long.
                The S320R uses an S3327 (most common) or the S3228UL (metal ) Element
                The 660R-RAC-02 (metal base w drain) uses a S3232UL filter and should be almost six inches long. Maybe after you get the correct filter for the base things might work better? I have attached a website that has the specs.
                Hope this helps - good luck

                  I have had a similar problem with a 150 hp Yamaha outboard. It never occurred to me or anyone else that the Raycor filter might have had anything to do with the problem. Like you, I changed everything in the fuel delivery system there was: different lines, tanks, no quick connects, and finally, even the really expensive CDI box. The problem was sporadic so no one could pin it down. I haven't used the rig for a couple of years due to fuel prices but I am going to take it out, bypass the Raycor, and see what happens.

                    Just a guess here but I have spent a lot of time dealing with fuel issues over the years. Sounds like it may be the only thing that you haven't checked in your trouble shooting - my first guess would have been the pick up tube but you replaced that.

                    You may have a stuck check valve (anti siphon valve) in the line (a spring loaded ball valve that prevents fuel from flowing backwards) This would allow the filter to drain back into the tank and the boat won't run with a high demand for fuel until the filter is refilled (sucks air) - Same effect as running it dry on one tank quickly switching to another tank and immediately trying to get back on step. I know from experience that it doesn't take much to have this check ball stick.

                    I have used the raycor filters for years and they cured all problems I had previously. I have had them shut down with an excess of water, poured out the water and ran again with the same filter. From my experience I would have a hard time believing it was a new filter element causing the problem.

                    Good Luck

                      Mine pickup tube dos not have a ck vale in it, The boat will always just fire right up idle perfect, used to in my old boat take them off dump them run again, thought new boat new filter,Now than akfishnut got this right on the head, I just crawled underneath trap on boat looked on mount and have my spare in my hand Sure enough it is not a 320R-Rac_02 It reads on the box it is a replacement element for?? It is only 4 1/8 long And it has add, stated 3times the media.Outboard use only... Hum... I will be looking for 3232 today, I,m at this dealer everyday..Thank you for the tip!!!!!! Now only 6weeks to try it out i will let you know how it go Thaks Jeff

                        The pickup tube would not have the check valve - it would be at the tank, at the filter, or in line - I believe by law all boat manufactures have to put a check valve in. With an empty filter the boat will fire up and run at an idle on the fuel in the carb and it won't sputter until the huge demand on an empty filter hits when you power up to go on step.

                        Sounds like you have it figured out anyway - but I would keep this in mind - I would think an incorrect filter would either work all the time or fail all the time - not just part of the time right after start up.

                        This link is to West Marine and will show a picture of the valve and refers to the law.

                        Good luck and please let us know when you get it figured out - I can always use education on this with the poor quality of fuel we are somtimes forced to use out in the wilds.

                          Part,no# RACS3228UL is Rated at 60 GPH the one for the 660 is rated at 90GPH - Both are way more than required for a 350Chevy. If your boat ran good for a year I would assume the smaller filter sealed fine on the 660 mount.

                          I run the RACS3228UL filter on my 351 Windsor and it is plenty big - The highest flow rate I have ever seen is 27 gph while coming on step with 2 moose and loaded down.

                            Another Idea to Consider Re Racor Filter

                            You might have been getting water into your carburetor from the bottom of the Racor housing. It is designed to coalesce the water out of the fuel, and drop it to the bottom of the housing. Up to a point, it won't cause any trouble, but once a few ounces of water accumulates, the engine will see water at any throttle setting except maybe idle. Apparently the higher fuel flow picks the water up from the bottom of the housing.

                            Sometimes the problem can be solved just by draining about a cup or so of fuel out of the filter. I carry a disposable storage container (Glad, TakeAlong, etc.) that will hold a couple of cups, fits under the filter housing, and will allow me to get it out of the engine compartment without spilling. If I need to drain the filter, I use the container to catch the drainage, and then funnel the drained water/fuel into a clear plastic pop bottle for disposal once I get back to port. I definitely recommend installing an in-line filter ahead of the Racor, since the Racor elements are relatively expensive. The in-line won't catch water, but it will keep suspended solids from plugging the Racor. I change out the in-line filter every 25 hours of operation.

                            By the way, if the in-line filter sees water, it will plug very quickly, so you should always carry a couple of spares with you.

                            Good Luck!

                              Call Racor Tech Services

                              SusitnaAK

                              In the Racor products book there used to be a phone number for Racor Tech Service. If you could get that number you would be able to talk with a racor service tech. They have some excellent trained personnel that might shed some light on your problems.
                              You would have to find a dealer that has a Racor book.

                              Also:
                              I would recommend that you go down to Ace Supply (E 5th Ave ANCH) and purchase a bottle of water finding paste - this is a brown paste that turns bright purple when water touchs it. You can place a little on the end of a stick and dip it in the fuel - it will show the exact level of any water
                              that might be in the bottom of the tank. Keep in mind you need to have the boat motionless for several hours for all the water to settle out.
                              If you can access the tank, I would tip the bow real high and test the back corner of the tank.
                              How stupid is it to be wasting tons of salmon and halibut as bycatch in the Bering Sea and then have the coastal villages hollaring they have no food? It's got to stop!
