Default tap location for fuel pressure sensor

hey guys

i was just wondering where to put the probe for my fuel pressure gauge...i was told to tap the line right after the rising rate fuel pressure regulator...i was also wondering on what you guys used because my gauge didn't seem to come with a T or anything...looks like i would have to source something out from home depot...thanks

most people tap the line coming right out of the fuel filter before it goes to the fuel rails. Anywhere between there and the FPR should be fine. if you tap it after the FPR, then you'll be getting the pressure as the fuel is going back to the tank.... not much, and won't tell you anything.

thanx...the confusing part is that my gauge is just a general pressure gauge from Apex'i....it saids it mainly for oil pressure but fuel pressure is optional....i was wondering what should i use to tap into the fuel line...perhaps i have to find a pre-threaded T somewhere?? cause the probe basically looks like a round tip with threads on it...

Also, if you are going to put that gauge inside the vehicle.
It's highly recommended that you get an isolator:

Yes, they are expensive, but the last time I checked it's not real fun to have 40+psi of fuel squirting around in the "cockpit"

EDIT: it sounds like you have an electronic sender, disregard isolator

^^^ What he said... It shouldn't take you more than 10 mins under the hood and may be 20 mins to make it look nice and wire it. Just get the barbwire NPT adapters from Pepboys, cut the line out of the filter, put the barbwire adapters inline, and you are pretty much done.

Barbwire, eh? Don't you mean hose barb? And yes, that is the easiest place to hook up a fuel pressure gauge.
