I am going to put my SU fuel pump, now rebuilt and ticking merrily away on
the test bed I made, back on.
I currently have a facet newer style with the black plastic body. I think I
may leave that pump in line with a switch to turn it on as a back up. My
only question is should I put it in between the SU pump and carbs, or SU
pump and tank, only advantage I can think of is that if it is between pump
and tank if the SU fails the back-up will be primed, vs. it likely being
dry if I were to put it in line after the SU. Don't know if it is better to
push or pull gas through the back up pump? Or doesn't matter.
Any thoughts or advice appreciated. I am also considering just throwing the
spare in the trunk with some rubber hose so it can be installed if needed
(usually when I have a spare in the trunk the old part suddenly becomes more
reliable!)
