Hmmm, I didn't think of running a return line. I like that idea, thanks Rich. Does the return line have to be the same size as the fuel line? I have Barry R. on the FE Forum telling me that 3/8" is fine with pusher electrics. Nothing is easy, huh?
I'm still stuck on the idea that with 3/8" fittings it's useless to go to half inch line as only enough fuel to pass through the restrictive fitting size will flow. Is this a correct assumption? I would just run 1/2" since it's no big deal, but that greatly restricts the choices on mechanical pumps used at the front end of this setup. The only one I know of with 1/2" fittings on it is the RobbMc unit, and it's a $300 piece, sort of steep. Long story why I want a mechanical unit as well, but I do want one in there.
