Hi

Does anyone know how to check fuel pressure that go to the fuel rail?


1. My car is non turbo, If i would like to change the fuel pump to be the bigger one, do i need to modify electric wire?

2. if I buy the high performance fuel regulator , which brand I can put it at the same place as the original one?

3. where can i buy the MFI and fuel pump relay for cheap?

thank you
AJ
