Fuel Pressure Gauge

[Dave04]

What do you think?
I have a Westech fuel pressure gauge. Measures before the CP3. In tank warranty replacement. Normal measures 10 to 12 lbs. Gauge died for about 3 weeks didn't have time to check it out. Just didn't registered anything. Then it started working again. Now pressure in 8 or 9 sometimes as low as 5 or 6 at idle. Down a bit during take off. 120K on current life pump.

Guessing it is dieing???

I would check pressure with a direct pressure gauge to verify pressure....i dont trust electrical sending unit gauges

Have you changed your fuel filter lately?
Some people do use their fuel pressure gauge as a indicator for fuel filter change.

I will try to check it with a DP gauge. I change the fuel filter every oil change. 10k or year which ever is first.
