I have a conundrum...I would like to flush my boats fuel tank but I don't have the ability to remove it from my 1984 Bayllner 2450 Ciera. I have removed as much fuel as possible using an auxiliary fuel pump but of course there is still some remaining at the bottom with a decent amount of what I believe is scale and dirt sediment. I really want to remove all of the sediment as I an because I believe it is the culprit to some boating issue I experienced this summer with me losing power in choppy waves and me having to shut down my boat to let the dirt drain from the pick-up tube and the restart and run a bit more until it lose power again. I believe it to be due to the fuel because I checked my Racor fuel filter when I was experience the loss of power and open up the bottom drain plug and no fuel came out leading me to believe something had plugged off the pick-up tube. When I made it back to dry land I did find scale on the pick-up tube filer and in the pick-up tube itself.
After all of that I figured I would flush my fuel tank as best a possible to get rid of all the debris I could. Which leads me to my original question. Does anyone have any creative ideas? Should I drill a hole in the fiberglass covering my tank and then into the bottom of my stainless steel tank as a drain? Are there any companies that would perform a good flush for me? The biggest opening I have on the top of my tank is about 1.5" in diameter so it is a bit difficult for me to get much done from the top with my remedial skills and tools
I am open to any and all suggestions. Thanks in advance
