I bought SUM-800160, summit's fuel pressure guage for my 89 coupe. I figured it would come with the fittings to connect it to the schrader valve but it was just the guage. What do I need to connect it to the scrhader valve and where can I get these fittings? Thanks for the help........ :shrug:

summit has the fitting... its a 1/16 fitting into the schrader valve and whatever size you need for the gauge to connect to it. its a NOS part # i bought one from summit that was autometer but mine was 1/16 into -4an for my line. so they are going to be different. be very very very careful when tightening the fitting. they are brass and tend to snap when over tightened. good luck
 
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. I ran a piece of SS (stainless steel) braided hose to a brass T 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. I used a cheap industrial gauge from MSC Direct ( http://www.mscdirect.com/PDF.process?pdf=4588&Keyword=Y ). It works great and was cheaper than 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 SS 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 SS braided hose, the SS braided hose just looks nice. I got mine for $4 at a place that sells industrial and military surplus parts of all kinds. The SS 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.
 
My problem is, the guage that I bought didnt come with that fitting that goes in between the actual guage and the schrader valve. (For ones that actually mount on the rail). And Summit sells them, but Its gonna be like $18 for the fitting and handling fee. Can I find this anywhere else? Isnt it just a 1/16NPTmale to 1/4female fitting? Someone let me know before I order this thing...........
