Hello all been reading this site for a few years now got a lot of info on trucks Thank-you all for your expertize. I have a problem with my 08 F250 Super Duty
I have an auxl fuel tank in my truck the fuel line hooks into the filler neck, as fuel is being comsumed out of the factory tank the auxl tank feeds, by gravity into the factory, so by that my fuel gauge shows full until all the fuel is used up in the auxl tank and then the gauge begins to work. Now heve is the problem. I have a valve to shut off the auxl tank if I want to normally I leave it open to feed into the factory. but sometimes after both tanks are full fuel begins to leak out of the factory tank, like there is a vent or loose line dosen't leak everytime.
My question is. Is there a vent on top of the factory tank, It's not leaking around where the filler neck or around where the gauge fits in the top of the tank. It's leaking near the front of the factroy tank at the lower part of the top (hard to see between the frame rails) Does anyone have pictures of the top of the tank. Maybe someone has run into this problem before. Help is appericated
