where is the inlet test port on 2001i found the test port for the outlet is the inlet on the banjo bolt or is it under the fuel filter and what should the pressure be on the outlet side i orderd a in cab guage from peirs but i have a lot of driving to do be for it gets here the banjo bolt on the inlet side does not have a valve i know i have ben asking a lot about this but all the talk about the lift pump going bad i cant sleep at night till i find out if it is good or bad or week or?

 

There is a schrader valve on the fuel injection pump. I think in an 01 that is the easiest place to test. The other option is to use a tapped banjo on the outlet of the fuel filter. (bottom). Once you get your guages you should have instructions and the hookup at the bottom of the fuel filter is simple. You need the guage on the outlet side of the fuel filter because then if you have bad pressure due to a clogged filter it will show up. Another possibility is to get the tapped fuel filter cap from geno's garage. Hope I didn't confuse you too much!! Pressure should be 12+ at idle and 7 min at full throttle. You can get by with 5 full throttle but that is bare min. Normal for good pump is 13-14 idle, 11-12 cruise and 8-9 full throttle.

 

i have 1or 2 psi at the schrader valve on the injection pump with a new filter i take it that is a bad sign is the left pump a waranty item it is 2001 with 87ki am the second owner

 

yeah, you should have more pressure there. I have my FP hooked up at the schrader valve and I get 12-14 at idle, 8-10 at cruise. Make sure you don't over tighten the hose ot the schrader valve.

You need the "in service date" to know if you still have warranty. Mine is done in 10 days.

 

how do get the in service date ?

 

Thats the day the truck was purchased new and titled. You can check with the sevice writer at the dealership and they can tell you the in-service date. They will look it up by the VIN.
