u know wat psi a 95 3100 would be?

43.5 is for '99 and older. 55 is for '00+

I'd use the 00+ FPR, you'll need all the fuel you can get for the 3500. 3500's came stock with 24lb/hr. with 22.5 3400 injectors you are already getting close to their limit.

Actually the '99 3400 injectors are 19 lb/hr @ 43.5 PSI.

Correct, but they are 22.5 @ 55 PSI
