Do our trucks have a schrader valve or anything on the fuel lines where I can test fuel pressure? If no, how would I go about testing fuel pressure? What pressure should the 3.4L be running at? Thanks.
What is OTC??? If you go the other route (Ting the fuel line), where would you make the cut. Couldn't you just install a schrader valve and leave the T in at all times?? That way you have easy access. Where would I be able to get a T fitting? Thanks.Gadget said:There is a special service tool available from OTC. It uses a banjo fitting and a longer banjo bolt so you can attach it on the end of the fuel rail.
Or you can simply cut the high pressure hose and T a fitting into it for the pressure gauge. When you are done, you just patch the cut with small piece of pipe and hose clamps. I had one set up for this and loaned it to a guy in FL about a year ago and he refuses to send it back.
The fuel pressure should be 43.5 all the time on these engines in stock configuration.
