Fuel press. gauge on 05's

[SSalzer]

Has anyone installed a fuel pressure gauge on their 04. 5 or 05? Is it worth the money if all I plan on doing is a box and exhaust?

I did on my 05. They don't cost very much more if you are doing other gauges anyway. Nice to know that all is well as far as fuel pressure goes with all the stories you hear on that subject. 05 doesn't have a lift pump though, it is a pusher pump in the tank.



On mine the fuel pressure is always about 8 or 9 psi. One of these days I'll turn the boxes up and see how low it goes when really getting on it.

I am running one on my 05. With the tst twins program, anything over level 6-6 starts really drawing the pressure down. Level 8-8 will take the pressure down to 1 psi, which I think is still better than the old lift pump pressure
