John would know for sure, but as a general rule: definitely no more than 4 psi when switching to an electric pump in a carbureted engine. Any more can over-power the float/needle, and you'll be chasing rough running/flooding issues. I had a 7 psi
pump in an Allis 180 for a brief period to get me through haying season when the diaphragm in the mechanical one failed: It would run fine under a load when it was using more fuel, but would flood and run erratically if left sitting at idle (not
using much fuel) as it would slowly over power the float and flood. Switched to a 4 psi and all the problems went away.

Since then I've rebuilt the original mechanical pump. Nothing wrong with the mechanical pumps: Some folks will say that switching to electric makes a world of difference, but they likely have something else wrong with their fuel system. If you want
to rebuild the original, contact 'Then and Now Automotive'. They have kits to rebuild almost every mechanical pump imaginable - even if they don't show it in their catalog they likely can put a kit together if you call them.
