that's enough to get you by but, when you concider the aftermarket pumps are giving you closer to 50psi ( when adjusted that way ), it's pretty bad.

I thought you were installing a FASS ??

11 PSI doing what? Idle, WOT or something else. At WOT 11psi is good, at Idle, not so good.

at WOT 11psi would be as I said... ok. At least you're not running it dry. If you have 11psi at idle, your WOT will be closer to zero. If you can, find out what the spec is for your pump that would help tell whether 11 is good or not. I can tell you right now it's not if you plan or running any boxes. I saw mine get down to 3psi at WOT and that's a brand new pump which is pretty sad. Now with my walbro, I'm at 22psi all the time and can go up to 45.

K what's the specs on a 03 dodge if you don't mind Triton. I'm going to upgrade to fass. newb question what is WOT. Work On Turbo? or truck? meaning engine is being worked? I hope to install my fuel pressure gauge and I need to know what too watch out for. also where do you find all these specs. will come in handy so I can pay attention to everythign and know it's reading all good or all bad or too late my engine is all gone! ha ha hopefully not.
