I don't have a fuel pressure gauge inline so I don't know how to set my fuel pressure reg, can anyone give me an idea of how many turns from max that 45psi or so is? I want to drive it this week, and can't wait for the parts i need for testing pressure.

 

There is no way to tell, each car is slightly different. 2 turns on mine might need 3 on yours, this is extremely important to set your pressure correctly so be patient. If you are in a huge hurry then go to the auto parts store and buy a test gauge, you will have to plumb it inline some how of course. Do you have the -6 or -10 SX regulator? The -10 has a gauge port on it (1/8" NPT), which should be easy to find a gauge for. If not Summit Racing always gets stuff to me in about two days.. HTH.

 

how do you tell if it is 6 or 10an?

 

When you ordered it didn't you specify which size?? You should be able to tell, 10an is huge... You probably have the 6an. How do you have it setup? You had to have boughten fittings/hoses of it.... which would correspond to its size.

 

How about just looking at the FPR to see if it has a plugged 1/8 NPT port in the front of it? The plug on mine was a socket head -- remove with an "Allen" wrench (hex key). That is where you connect the pressure gauge. I would think that even auto parts stores would have suitable gauges.

ah, i have the allen head on mine! Hah! I have the gauge, thanks guys!
