My fuel pressure gauge shows 11-12 psi at idle and 6-7 at full throttle.
Stock LP.
What does everyone think?

 

With my FASS system, I get 16-17 lbs of fuel pressure at idle. Not sure what it was before as I did gauges at the same time.

 

Sounds like a stock system, mine runs 12-14 psi at idle, with a smarty and injectors I can drag mine down to 4 psi at WOT.

 

Sounds like it's a little on the low side.
Borderline for now, but keep a careful eye on it, and start shopping for a replacement.

I see 15-16 @ idle & 9-10 at WOT.
Stock lift pump w/ Scotty's Smart Fuel System.

 

Mine is about the same, can drop it down to 5psi at WOT, stock lift pump. ordered a Scotty fuel kit yesterday.

 

Scotty's fuel kit will help a lot.

If you have 8psi @ wot, I'd say you're fine. A little below that is OK, just don't like it drop to 1 or 2 for any considerable amount of time.

jh

 

looks good to me

 

When it gets to 4-5 lbs. it is time for action. OK till then.

 

I know where you live! And I wouldn't hesitate to replace it asap!

 

Yep,

Most FP gauges that you will find rated for diesel start showing the little red warning line right around 5psi. With that said 5psi was the limit a couple years ago, but I hear more and more folks saying that anything under 8psi will require attention rather soon.
