fuel return line best options please

[sweetk30]

i have to plumb a return line for the fuel injection setup on my old car and was looking for the best way to plumb the return line. it has a small sender with no real room for a second line in to it. thanks for any and all ideas .

well info for ya to help me : 73 ford mustang and new gas tank no fuel yet. sender is in the side and no real room for bulkhead fitting on top of tank as its under the trunk pan. i know its a ford but its moms can so any help would keep me from the dog house if you know what i am saying thanks.

"T" into the gas filler tube.That's what I did when I put in my TPI.

Depending on what it is, you may be able to find a sender from a different model that will fit the tank and has the extra return line.

You can also get sealed bulkhead connectors to add a return line in the top. I've seen them for fuel cells and I don't know why it wouldn't work for a regular tank as long as you have a flat spot to mount it.

One thing to think about with the return in the filler neck, or a bulkhead fitting that does not have an extension to the bottom, will the aeration be a problem? Particularly when the fuel volume is low? I'm not real sure. It would be terrible with diesel fuel, not sure how bad it would be for gasoline, but I'm pretty sure it's not a good thing...
