How do you know if a pressure regulator is bad and you don't have the $100 pressure gauge to test the pressure at the schrader valve? I have gas squirting out of the valve, but I dunno if it's enough, I just changed the fuel pump because the old one crapped out and a new filter, new plugs, wires, and a cap and just because I wasnt sure I took the airbox off to make sure it had plenty of air and it sucks really good at the MAF. I pulled a plug off and it has a faint smell of gas from trying to start it, but nothing too extreme.

A fuel preesure test gauge can be rented/borrowed from AutoZone or any of the other major auto parts chain stores.
What to build your own for less than $35?

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 (Industrial Supply Equipment from MSC Industrial Supply 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. Decide how much you want to spend and what size gauge you want and they have it
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.
