<VV> Fuel Pump Question

[Bob & Kathy Gilbert]

This is a follow on to my earlier trials with a car that seems to be starved
of gas.

I have an in-line electric fuel pump and decided to mount it at the rear but
at a point in line with, if not lower than, the lowest point on the fuel
tank.

Earlier, about half the replies I got said it is OK to mount it there while
the other half (and the instructions) said mount it as close to the tank as
possible.

My question is - why should it matter as long as the pump is below the
bottom of the tank? Whether it sucks from a tank 8 feet away and pumps to a
carb about 4 feet away or sucks from a tank a few inches away and pumps to a
carb 12 feet away shouldn't matter - or does it? Does the pump work in some
sort of asymmetrical fashion?

Thanks,
Bob
