what should the fuel pressure on the feed banjo bolt on the injector pump be at in idle??
stock pump
bumped pump

crusing down the highway at 60-65
stock pump
bumped pump

WOT
stock pump
bumped pump

i know this is the scale for 98.5 and up 24 valves but is this about the same for the 12 valves???
9-15 excellent pressure
4-9 weak pump or dirty filter
2-4 will run but rough need to replace pump

is this about right???????


thanks

 

12 valves run a lot higher fuel preasure's than 24v's.

 

there supposed to run like 17-22 psi at idle correct????? and about 25-30 psi at WOT with no load.

right??

thanks

 

Specifications are 17 - 22 psi at idle and 25 - 35 psi at 2500 rpm (no load).
