[Healeys] Fuel Pump Back Aup

[Greg Lemon]

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!)
