We assume your FPR will not have a hook-up for a gauge? I ask because if you have not purchased one, that could be a consideration.

Good luck.

its the red holley adj fpr and its mounted on the stock fuel rail so im assuming the only way I can check for fp is off the schrader valve? which is hooked up to my fuel line for my solenoid for my wet kit so id like to run a gauge from the schrader valve to the fuel line for my wet kit if possible, if not ill just buy a cheap $20 fuel pressure tester and disconnect the fuel line so i can get access to the schrader valve and check the pressure then hook it back up when i go to race. thanks

ASK and you shall receive...

Fuel pressure gauge adapter fittings:
http://www.holley.com/products.asp?product=17945NOS AN 4 to 1/16” pipe
http://www.holley.com/products.asp?product=16785NOS 1/16” male pipe to 1/8” female pipe

Or
See http://www.autometer.com/cat_accessorieslist.aspx?pid=10

I made my own pressure gauge and holder. I bought the NOS or Autometer adapter that you screw into the place on the fuel line where the schrader valve goes. You have to remove the Schrader valve, but save it, since you will reuse it. I ran a piece of SS (stainless steel) braided hose to a 1/8” pipe brass tee fitting that I mounted on the fender well by the MAF. I made a mount bracket out of aluminum angle I got from Home depot and bolted it to the fender well. Then I mounted the brass tee to it with some machine screws and a plate. I sandwiched the brass tee between the aluminum angle and a flat piece of aluminum that I trimmed off the extra aluminum angle. Three screws laid out in a triangle pattern go through both pieces of aluminum to clamp the tee in place. Put the Schrader valve in the spare port of the brass tee. I used a cheap industrial gauge from MSC Direct (http://www1.mscdirect.com/ P/N 56468499). It works great and was cheaper than (less than $6) anything Summit had.

If you look through the MSC Direct catalog, you can find any type of gauge you want, including liquid filled. You only need a liquid filled gauge if you mount it directly on the engine. The liquid filling dampens out the vibrations.

You can buy the Autometer Stainless Steel braided hose for like $60. Or a local shop that makes hydraulic hose assemblies can make it for you at a cheaper price. Ordinary low pressure hydraulic hose can be used in place of the Stainless Steel braided hose, the Stainless Steel braided hose just looks nice. I got mine for $4 at a place that sells industrial and military surplus parts of all kinds. The Stainless Steel braided hose goes for about $3.60 a foot and the fittings are probably about $5-$8 each. You can make your own and save some $$$, the shops may have a setup or labor charge to fabricate the hose assembly.
