Chuck,
I found a low pressure pump from the local auto parts store. Mounted next to tank. No regulator needed; about $40. Line pressure is about 3 psi according to the PMO FP gauge. Make sure the required pressure is
downstream of any inline filters you install (there isn't that much leeway below 3 psi).
The cheapie $20 FP regulators can't be trusted to last. As these responses indicate, the Holly is a good choice if you need one.

Rev. 10/12: I should have used the word
"upstream" or on the carb side of the filter. Sorry for the incorrect description.
