Hello I have a 65 Pontiac LeMans 326 v8 I started experiencing fuel bleed back from carburetor back towards gas tank, 2 barrel Carter carburetor I replace the pump its made no change I have an inline filter right before it goes into the carburetor so I can watch it fill up and then after I turn it off and even when I'm driving it will bleed back and I'll have to crank it several times for the gas to come back up to the inline fuel filter at the carburetor does anyone have any ideas?
CPL...does it have a fuel return line? The AC cars, like mine had a fuel rerun line that returned fuel at the filter back to the tank. It was there to keep the fuel cooler, as an AC condenser dumps a lot more heat and a compressor puts more load on the engine..
So that is first...just one fuel line or two? The return line if you have it is not a vapor line it returns fuel volume not used at the carb....
Maybe having to crank it a little is related there but that could also be many other things, throttle set wrong, plug gaps too wide, choke not set right, etc
Thanks looks like it was a clogged filter right inside the carb were the line screws in.the little round paper one... I do have ac however it's not in but yes I do have that return line it was disconnected and plugged before I got the car.my question is were exactly dose it connect?and what psi radiator cap should I be running?326 v8,rebuilt radiator rebiult.
Thanks for your time
It happened again once it heats up it beads back car dies I have to crank it a few times to get gas back up.what can you tell me about that return line how is it hooked into the system.mine is disconnected.any help will be great thanks
By all means use the return line! It will solve your issues. The filter mounts to a bracket on the T stat housing, and the 1/4 inch line runs from the filter under the alternator and is bolted to the timing cover. A rubber line connects to the 1/4 line in the frame rail. I have pics of mine, just not on this PC. Your fuel will run a whole lot cooler, eliminating vapor lock and all kinds of issues with today's crap gas. There is no downside running a vapor return fuel line system: you get cooler fuel and another, real filter.
Dose the return in line fuel filter have to go up by the carb,or can it be down on the frame rail by the fuel and return lines?
