Thanks man.

OK, that makes sense. You sold me on the placement location near the tank right near where the filter is located. That nice open spot underhood had me in "wishful thinking mode.

So which of the two models (1.5-4 PSI vs. 4-7 PSI) is a better choice then? Again, no future engine mods are planned.

The factory mechanical pump is 2.8-4.2 PSI/20-29 kPa discharge pressure. I am getting that straight from the 89 factory shop manual that I have.

I really don't want to "overpressure" the Weber anymore, that is the reason for this exercise to be honest and it seems to me that the 4-7 PSI model will possibly (probably?) do that.

I doubt the pump could be exchanged after it had been installed...so I'm looking for the best educated guess here.
