[T3] Ý: [T3] Tony Adams: gas gauge
Hello everyone , listen to Jim he know what he talking about. about 4 years
ago I have this
problem , my car seems to run very bad and it was becouse the fuel tank was
full of water (
and the carbs too) , after rebuilding the carbs and cleaning the fuel tank I
call T3D and order this over flow rubber tube , thay send me a used one with
cracks and holes like my
original , this was the last time that I order from them. so I just modified
a rubber tube that
I bought at the local parts store , not original but good for me and for my
car.

> now also need to at least check, and probably fix, the vent system.
