My 430 is a 1986 and I want to replace the old fuel transfer pump due to age. My question is: What is the max pressure that the injector pump should have from the transfer pump.I am not looking for extra HP just a happy injector pump.I would like to buy a pump from my local NAPA store...Max psi/gph?

I think the pumps are like what you would use on a carbureted engine, so 1-3psi type range.
I definitely wouldnt use a gasoline fuel injection pump as those are 40-100 psi!
I was able to make my 430 engine run on the stand with just gravity feed, not sure if that would provide enough fuel under load, but that was basically 0psi and the engine ran fine.
