2003 Rail Relief Valve

[5POINT9]

I think I may of popped mine. . I was running the diablo predator and puck without the stack tune. Before this, I would get 10-12k cruising pressure, 5-6k idle. Now, after a few hard runs, I am at 8k cruising and 4k idle. Truck seems to be doing ok, but the pressure is much lower at cruise and during accel.

What are the symptoms of a popped/worn valve? Who has them new/rebuilt at a decent price?



Thanks!

When my rail pressure valve went on the '05, I had a huge loss of power and lots of smoke on heavy acceleration. The truck was a dog. I couldn't find a replacement at a reasonable price, so I got a cap from Floor it Diesel and haven't had any problems since.
