Hello everyone.
I need some help. I have noticed that the fuel pressure gauge on my 87 GN has been showing a lower and lower pressure for the last few weeks. When I first start up it has went from 38 to 27 now. This has been over a several weeks period.
How do I diagnose what the problem is?
I am running an electric gauge (old cyberdyne) that was always very accurate. I also have a mechanical one that I am going to hook up. This should tell me if its just a gauge problem.
So if the gauge is correct, then I know it can be the pressure regulator(an adjustable kirban ) or the fuel pump (a walbro 307).
I know I saw a procedure to check which one it was but I can't find it now.Any help would be appreciated!
