Title: V6 fuel pressure and 3.0 blue injector's
Post by: Laliiii on August 31, 2020, 12:32:18 PM

I have got '97 calibra, fuel pump located inside the tank. I need to change fuel pump because it is slightly beeps and I am thinking in the pressure. Make sense to increase the 3.0 bar fuel pressure to 4.0 bar with standard Vectra fuel pressure regulator? Of course the fuel pump should be change for example 5.0 bar pump and higher flow rate capacity fuel pump.

Make sense to change the black injector's to the blue one's from Omega?
