Hi,

Anyone have any knowledge about what I'm being told may be a collapsed bladder in the fuel tank on my '77? I'm getting no fuel even though the fuel pump is good and the line has been replaced.

Thanks,

Larrywsr

A collapsed bladder wouldn't normally prevent fuel from making it to the carb, UNLESS....there's no fuel in the tank. If the bladder is deformed, it can cause the fuel gauge to read full, or half tank or whatever, but the tank may well be empty.
Have you tried adding fuel to the tank to see if that is the problem?

Are you sure that the pick up on the sending unit isn't plugged up? Or, there could be some doodoo in the line somewhere.

I'd check the sending unit and/ or blow out the fuel line.

Good luck

Paul
