Author Topic:   Possible Leak in fuel tank

I purchased an '87 Outrage 22 six week ago and am planning a major restoration in January. After filling the boat up with fuel last weekend, I've noticed a small amount of gasoline pumping overboard when I run the bilge pump in the aft starboard quarter. My question is if the tank is leaking would it overflow into that area? Or is it more likely that a fuel supply hose is leaking? Any suggestions?

The fact that fuel is showing up in the drain sump doesn't tell you much about its source. It could be the tank or it could be a hose or fitting that is leaking.

Any fuel tat escapes into the fuel tank cavity will drain to the rear drain sump even if the fuel tank cavity does not completely drain itself. This is because gasoline is much lighter than water and will float on top of any water that is retained in the fuel tank cavity. It will thus overflow into the rear sump.

Have the fuel hoses been replaced since the boat was new? This might be a good thing to do if not.

I believe the fuel hoses where replaced when the boat was repowered in '96. I'll be replacing them again when I repower in January. I'm very happy to hear that if the fuel tank where leaking it would leak into the rear splash well.

Abaco, the life expectancy of the original fuel tank is about fifteen years. Some may last twenty years, others will fail at ten, but lots seem to fail betwen 12 and 15 years. Knowing what I know now, if I were doing a comprehensive restoration and repower on a boat with a fifteen year old fuel tank, I would replace the tank while I had the boat apart. It's better to do it now, while the boat is disassembled, than six months from now when the sun is shining and you want to be using the boat.

Thanks for the advice. I will probably do just that.

I would be very careful running a bilge pump in an area with gas. Although unlikely, there is a tiny little spark created when a pump motor engages that could possibly ignitie gas and/or fumes. Good luck.
