Re: [T3] A few stock F.I. fuel pump questions

If you're going to try to use the FI pump with carbs,
you will most definitely need a return line into the
tank, as the FI pump will produce a LOT more fuel than
you'll need with carbs, and you cannot pump against a
"dead head" with this pump.  Excess fuel has to go
somewhere, so you'll need to use the return.

I'd advise against NOT trying to use the FI pump with
carbs.  I'd get a lower-volume pump and either put the
FI pump on the shelf for the day you decide to hook up
FI, or sell it.
