Does anyone know where I can get a "female" fitting to hook up a fuel pressure gauge to the schrader valve on the 500 EFI fuel rail? It's a much larger than standard diameter barrel for a schrader valve and I can't find a fitting for it-

take a look at auto meter 3280

Thanks, but the standard (tire valve) size schrader valve diameter is 1/8". The diameter on the fuel rail looks almost twice that. Besides, I was hoping someone know where I could get an actual Schrader fitting to mount on the end of a pressure gauge hose-

Call your local pipe supply shop or heating supply shop. as a pipe fitter we use these all the time in med gas and refrigeration set ups they should have them in various sizes

OK, thanks.

the 3280 is 1/8 NPT which is larger than the 1/8 inch u refer to, NPT national pipe thread,
