What fuel pressure gauge sould i get? One that reads 0-15, 0-30 or 0-100?

 

0-100. Stock pressure at idle is about 52 psi on my truck and runs up to better than 70 at 12 PSI of boost. An 04 or newer should be about 62 psi or thereabout. Going from memory so I could be off a little on the 04+.

 

+1 100psi.
Make sure it's electrical if going in the cab!

 

Cool i wanted to make sure. I think im going to get a trans temp and F/P gauge soon..

 

Dont be l ike some rednecks here and put a regular gauge in the cab withthe fuel line!!!
