Is there a Vortec 454 fuel pressure regulator?
Is there a Vortec 454 fuel pressure regulator?
The vortec 454 does not have the same injectors as the small block vortec. It uses the same type injector LT1 and TPI engines. They are buried under the plenum. Do you have any signs of fuel in vacuum line to the regulator? Does the fuel pressure at idle seem steady?
Why is the FP regulator leaking on my 7.4 Vortec?
If they’re pegged at +25 then the FP regulator is leaking. Very very common issue on the 7.4’s. If you don’t have scanner access connect a FP gauge, cycle the fuel pump a couple times and then watch the gauge for drop off. If it drops more than about 10 PSI in 20 minutes or so the reg is leaking into the intake.
What kind of pressure regulator does a Camaro have?
2005 CBR 1000RR…”mostly stock”. 1968 camaro… “in the works”. OK lets start with the basics. (1) Check your compression, the fastest way to see if they are all at least even with each other is to disable the ignition and roll it over with the starter.
How can I Check my fuel pressure regulator?
(1) Check your compression, the fastest way to see if they are all at least even with each other is to disable the ignition and roll it over with the starter. If it sounds like a nice even rhythm its probably ok.

How does the fuel pump work in a 454 engine?
It pumps fuel to the throttle body and the direct fuel injector system through the fuel supply line and then through an in-line fuel filter. The pump is designed to provide pressurized fuel at 125 kPa (18psi.) A pressure regulator in the TBI keeps fuel available to the injectors at a constant pressure between 62 and 90 kpa. (9 to 13psi.)

Where are the fuel injectors located in a 454 engine?
The throttle portion of both the TBI units may contain ports located above, or below the throttle valve. These ports generate the vacuum signals for the exhaust gas recirculation (EGR) valve, MAP sensor and the canister purger purge system. The fuel injectors are solenoid-operated device, controlled by the ECM.
Where is the fuel pump located in a 454 engine?
Evaporation emission control system. The injector fuel control systems have a electric fuel pump, located in the fuel tank on the gauge sending unit. It pumps fuel to the throttle body and the direct fuel injector system through the fuel supply line and then through an in-line fuel filter.
What kind of fuel delivery system does a 454 engine use?
This is an aspirated fuel delivery system with the addition of a mixture control system controlled by the ECM. It is not even close to the ECM used today. This fuel delivery system uses a mechanical fuel pump with the addition of an inline lift pump between this pump and gas tank on some systems to help prevent vapor-lock.
