Fuel Pressure Gauge

[LarryJewell]

A while back I hooked up my fuel pressure gauge to the to the test port to the rear of the alternator. Ever since, the gauge needle has been a little bouncy/erratic on normal acceleration. I installed this 2' section of braided hose and everything is good now.

Makes sense Larry.

What did it have before Larry?

 

[LarryJewell]

the gauges sensor screwed into the fitting where the braided line is in the pics.

I will have to do this as mine is doing the same thing

Huh, my LB7 has a big "R134a" lookin test port next to my alternator. I have a diagnostic type gauge the hooks to the quick-connect test port, no flutter on mine. My lift pump is running about 15psi

 

[fishsmith]

my new one is running about 15 and it is not doing it but my tts pumps would.
