Fuel Return Line ?
Ok, brain stall. My fuel pump only has one inlet. So now when the fuel tank is full and car is pointing down, gas comes out the return. I've had an electric pump on for such a long time I don't remember. Should I just cap it off? On 68's the gas cap is sealed, won't this cause problem?

The return line connects at the top of the tank, be hard for gas to come back out. Should just act as a vent.
If the cap is vented should not be a problem in caping the return line.
Do you have the vapor line on the drivers side?

Then I either have a year change or some other tank. No vent line and the sender is on the bottom where the fuel line comes from.
Now that I think of it I don't have a fuel return line at all. Must be original since whos taking that out!
I think what you should do instead is convert to fuel injection. You already have the fuel return.

Tom's got it right. Tripower (Holley) equipped cars did NOT have the return line from the factory. Rochester Q Jets DID have the return line.
Now, if things have been modified, all bets are off.
