Posted this over at the Comanche Club - it applies here too.
I was checking the fuel pressure today and unscrewed the Schrader valve cap to attach the pressure gauge. The cap was full of fuel! So I unscrewed the valve core and it's rubber seal around the stem was completely disintegrated. I'm guessing I must have had a pneumatic valve stem not rated for fuel and with today's ethanol loaded fuel, it rotted out. Lucky the cap was on tight or things might have got interesting.
I ordered the below Schrader valve and cap rated for fuel injection HERE (http://www.dieselorings.com/schrader-valve-fuel-injection-rated-1-8-mnpt.html) to be safe in the future. Until it comes in I'll keep my eye on the fuel rail for leaks. Might be a good idea for y'all to check also. :thumbsup:
