Hello All,
I just bought a new fuel pressure gauge. I installed it right on the FPR at the gauge port w/ a 90* fitting.
The strange thing is it reads 30 lbs. when the vac line is removed from the FPR or plugged into the FPR. No change in pressure reading.
When I adjust the set screw two to three full turns clockwise the lbs. will adjust a pound or two, that's it.
After turning the car off, the pressure gauge drops to 25 lbs. then after 20 to 30 minutes it goes to zero.
Any ideas?
Thanks.
