Small fuel pressure gauge

[VermontTy]

Summit used to sell a small fuel pressure gauge that would screw directly onto the schrader valve on the fuel rail; it was about 1" in diameter, and just had a stem on it, no hose, no electronics, etc. I can't seem to find it on their website anymore; it was around $20.

Does anyone know where I can get something like this? I just need a quick & dirty way to check fuel pressure. Thanks.

I'm in the same boat, everything I've seen (Mityvac@JCWhitney, Sunpro@Sears/Jegs) has the hoses etc (and is in the $40 range). Not that those are too high dollar, just seems like there should be something smaller/simpler, the search continues...

I wouldn't connect the guage directly on the schrader valve, becuase, the weight and center of gravity could posiible break off the valve...I used a hose to run mine. Just some food for thought!

This one I'd seen was seriously, about the diameter of a quarter, and was maybe 1.5" long with the stem and all; very small and lightweight. I don't think it'd harm anything. Suppose I'll keep looking.

Tim is right about not connecting a fuel pressure gauge directly to the fuel rail. Our fuel rail is weak and often (ie the past) a fuel presure guage will brake off. Even if it is light, the length of guage and engine vibrations will amplified the stress on the rail. With a guage, all the energy will have to be absord by the fuel rail, hose will have the ability to absorb it and the weight will be distributed else where. A hose is recommended for a electric fuel pressure guage sending as well.

I suppose that makes sense Dave. I didn't know they were so fragile.
