    Default How to clean out a fuel tank?

    My 84 gal tank in my Trophy Pro evidently has an algea issue in the tank. Had a history of water in the fuel when i bought the boat. That has been resolved. Now i plugged my pick up tube in the tank with algea and crude last weekend. Im looking for an effective and efficent way of cleaning the tank. Id hate to go through what i did this weekend in big water.
    Thanks in advance.

    After its empty, rinse it out well with Alumabrite or any other etching compound made for aluminum.
    She will be as good as new and it's too easy!

    Thanks for the reply Bk. But I've got a plastic tank. Any idea what chemical i should use in it? Still Alumabrite?

    Whatever you do, DON'T use bleach unless the tank is out of the boat and you can rinse is COMPLETELY clean. Bleach will kill your motor quicker than anything.

    I would not suggest Alumabrite. highly corrosive. If it’s like most Trophy Pros I think they build the boat around the tank so throughly cleaning will need to be done through the sending unit hole. Chemical treatments and a quick disconnect Racor filer with spares seems like the best option IMHO..

    Copy, didn't realize it was plastic. If it were Aluminum, cleaning with Alumabrite is too easy. Rinsing neutralizes the process and its what the pros do, to clean tanks to bare metal before welding. Works great.
    Post your method and results if you would when finished please.

    Thanks for the replies guys. Back to work for me so it'll be a couple weeks before i get to it. Hopefully I'll come up with the right chemical to treat it with, then I'll flush it very thoroughly and have several spare filters onboard afterward.
