2 1/2 psi fuel pressure

[Charlie ny]

I've had a few requests for 2 1/2 psi fuel pump springs. To my knowledge
there is not a spring available that fits this criteria. In my opinion many
things can effect pump pressure not the least of which is hard to detect
wear in the components. My average success rate with achieving 2 1/2
psi the first time with a rebuild is less than 50%. After an unsuccessful test
I will install a slightly weaker or stiffer spring depending on the the pressure
readings or failing that the lever or base....I never really know. Can't beat
real world testing.
