I do have one on my corvette. The thing to watch is that you don't plumb the return into the tank too close to the pickup line as the agetation caused by the returning fuel will then to send air into the pickup line if they are too close. Its also a good idea to have whomever modifies the tank for a return install a tube that causes the return fuel to come out near the bottom of the tank where it will be covered by fuel. This will also help avoid agetation and air getting into the pickup line. You will probably need to install larger lines to and from the tank to a regulator in the engine bay to ensure that you can hold a constant fuel pressure at all engine loads.

Great info Fred!

I really think I am going to build a bigger gas tank, and you are spot on with the return line. They installed mine right next to the pick-up

I will check the line size, but it is pretty big right now.

I need a gas tank ex-spert....

Thanks again Fred!
