Engine/Transmission (1994 - 1998) Fuel pressure gauge readings

[Bud Fox]

98 12v auto



just put in a new fuel pressure gauge and the readings are



idle is 19-20 psi



2000 rpm is 2400-2600



does the second reading seem a little low to you guys?





Thanks

What is the second reading at 2K RPMS?

Hey Bud, the factory service manual for '96 trucks calls for a minimum of 25 psi, with no more than a 5psi drop across the filter/separator. The 25 psi reading was to be taken at the inlet to the filter. I assume the info. would be the same for your '98 12 valve. If you believe you have a problem, check your lines from the tank and your overflow valve. Someone else may have some more suggestions as well. (I assume you meant 24 - 26 psi at 2,000 rpm's. )

Hey Bud,



Fuel Pressure: 18-24 psi at idle, 28-36 at 2000 rpm with no load. If you have never been to Dave Fritz's website, check http://dodgeram.org/ , it is full of information.

my 2000 rpm reading is 2400-2600 with no load.



Dont kow if it worth it to get a new overflow valve.



I also see new drop in pressure at 2000 rpm. it stays constant







Thanks
