73 Cuda fuel sender return port

[gman72]

The vent is the tube/port on the passengers side of the fuel tank. Pictures 2, 3 and 4 show the venting system. It is all contained in what you see in the picture and it vents into the frame rail. This venting system is a factory setup, I did not make the system myself.

So it terminates in the frame rail. I see. I thought it had to go all the way to the engine bay.

It seems to me changing out the fuel sender is probably my best bet. I bought a new fuel line and once that is connected with a proper filter, I would have to make room for this fuel vapor separator too. That is lot of connections. on a fuel line.

You can run a hose from the second (open) port on your sending unit to the line that runs where the charcoal canister used to be. Trim the old return port line back and connect with a rubber 1/4" hose to the fuel/vapor separator. The old line is 1/4" which is what my 440's return line is.

I was amazed that, that is the way they did it back then. The venting starts and ends back there.

However you do it, keep us posted.

Yeah, that is wild. I believe they make little safety valves in case of an accident so that fuel doesn't just slosh out of the vent line. I will definitely keep you guys in the loop.

I'll have to get the fuel vapor separator. Right now I have a traditional 2 port fuel filter.

Cool. Thanks, I appreciate it.

I wouldn't worry about the liquid fuel return. The car never had it originally and fuel vapor lock does not seem to be one of your issues.
I would concentrate on the fuel tank venting side of things.
