Losing fuel pressure
Hey guys. Long time, no see. Life has been entirely too crazy lately and no time for anything extra, let alone swinging by here. I have a quick question though regarding the FASS 95 I installed. About a month ago, I noticed the fuel pressure had decreased from 15 at idle to 13.5. It continued to decrease over a couple weeks time down to 11.5. I thought maybe a line was pinched on the gauge,but I found no problems there. I went ahead and replaced the inline filter a little prematurely in hopes that was the problem. It didn't fix it. All the research I have done is suggesting the bucket test. Is this the best next step or are there any other things I can try first?

Where do you have your fuel pressure sensor hooked in at? You may be able to stretch the fuel return spring and get more fuel pressure out of it.

I have it hooked in to the top of the fuel filter housing.

Coming by for a quick update, even if it makes me look silly. I took the pillar gauge pod out and pulled all hidden tube to my fuel pressure gauge today to double check it. Turns out that I had a good 8" of air in the line and when I installed I had only left the 2-3" for expansion. Found what looks to be dried antifreeze on the backside of the pod, so I it appears I had a very slow leak. Pulled it apart, topped it off, wrapped connections with plumbers tape and put it all back together. I am now running 16 psi. Time to use her again!:rocking:

Good to hear. Air in the line will give bad pressure readings.
|
It most certainly will. I am glad that it was a quick and cheap fix.:tu:
