    Default fuel return line?????

    (blown bbc with a mechanical clay smith pump) im installing an enderlee bypass on the fuel log instead of a regualtor and i was wondering if i could run the return line back in to the fuel line where the left and rt fuel tanks meet????

    It answered the question.
    The only shorter answer would have been "NO", but since yes is the correct answer, it seems OK.

    Dammit! My engine builder had bungs welded to the very front of my tanks so by the time any returned fuel made it back to the p/u it will have zero bubbles. Oh well its done. im gonna run a magnafuel 300 deal, and my friend Wedic just switched to the MF500 version. its actually very impressive watching how much fuel gets returned at idle, idle love to compare at WOT...

    A lot of EFI systems are that way now. One line from the tank, feeds the inlet of fuel pump. The return comes back and tees into the inlet of the pump. The 496s like mine come that way. The return just goes to the filter body secondary inlet. Keeps dual tanks simple. You don't need a six-hole tank valve. Just a normal three holer.

    Keep in mind, that by returning it to the tee line from the tank, its still under some pressure. Even if its the amount of weight pressure from the gasoline in the tanks, there is some pressure on the fuel line. Not all that easy to foam it while it has some pressure on it. When you dump it back in the tank, there is a possibilty for it to foam, specially of the dump is high. When returning it back to the tank it is best to have it go down a tube to the bottom of the tank, like a dip tube in a CG approved gas tank.
    EFI returns can be much higher pressure than a mechanical carb pump. If you are returning to the tank instead of like Beer described, then its best to stay away from the pickup, specially if its not dumped at the bottom of the tank.

    I perfer to have any return a small distance from the pump inlet like Beer described, back to the fuel filter or the OP back to the tank tee. But i have seen guys return right at the pump inlet on mechanical pump carb deals with no problem.

    Exactly. The thing I like about that setup is that the pickup IS at the bottom. Also, if there is a sock on the pickup, it would "backflush" it and keep the soot (if any) from gathering and plugging. Given, that is what a sock is for - but as long as the silage STAYS IN the tank and not into the line - it's a moot point.

    It just seems the more "efficient" way to go these days. The returned fuel - especially under heavy throttle - actually FEEDs the pump as opposed to just flying back to the tank. Some of the pumping loss actually gets neutralized.
