Engine/Transmission (1998.5 - 2002) Fuel Pressure Numbers

[kozowski]

OK, I finally got gauges installed (along with a Catcher) and I'm thinking I'm due for a lift pump. FP sender is attached to VP44 Schrader valve with an 18" (or there abouts) hose. I'm seeing 12 PSI at idle. I was able to drag it down to 3 PSI at WOT.



Am I right in figuring my LP is dieing?

I usually replace mine when it starts to get below 5 psi. Haven't any problems when i replace it early and i got a few mods done.
