What causes fuel leak in GMC 7.4L suburban?
If I remember correctly, your 7.4L has an “external” fuel pressure regulator. One common failure mode that I have seen with that kind of regulator is for the diaphragm to develop a leak and allow the excess fuel to bleed into the intake through the vacuum line attached to the FPR. Run the engine, then disconnect the vacuum line going to the FPR.
Do you need to replace FPR in GMC 7.4L suburban?
The 7.4 is SFI (sequential fuel injection). it has individual injectors mounted on the fuel rail under the upper intake manifold. no “spider” like the 4.3’s. and yes you need to remove upper intake to replace the fpr. So Gary, you’d say removing the upper intake (and putting it back) isn’t that tough of a job?
What should the pressure be on a GMC Suburban?
With the first on-off sequence the pressure came up to 30 psi or so – somewhat lower than spec of 56 – 62 psi. The second on off cycle brought the pressure up to just under 60 so right on target. The third on off cycle didn’t change a bit and it stayed at 60. Then I started the engine and let it run for 2 minutes of so.
