why just 15 psi?

[Triflex]

Just installed the 2nd fuel pressure gauge. Thought the first one was broken. Wondering why I only get 15 psi at the shreader valve. Truck runs ok.

15 psi is VERY low. Actually harmful to your injectors.

Are you sure you have the correct type of gauge?

Truck is running with 15psi or is that cranking pressure?

I agree 15 psi is way too low very harmful for injectors. I still think you have a bad FPR especialy scine the housing cracked and you jb welded it

[Triflex]

That could be it. I took the little screen out too to clean it up and there is a little plastic ball a little bigger than a bb as I remember in there too and seems like there was a little spring too. If there is mine is missing So I have ball, screen. Should it be ball,spring,screen?

Yes!

I ordered one gauge and sent it back, Ordered another from JEG`s by number and it was pictured as a fpg but it only says psi on the gauge, Goes to 100
