Permanent Fuel Rail Pressure Gauge
5 Attachment(s)
Here's a simple little mod that saves you time by enabling you to check your fuel pressure any time you want. The parts:
1.) A 0-60 PSI liquid-filled 1-1/2" fuel pressure gauge from Jegs, p/n 555-41012 2.) A brass 1/4" flare x 1/8" female NPT straight adapter fitting from here: http://www.casperselectronics.com/st...oducts_id=1337 Use teflon tape on the gauge pipe threads then snug it on the adapter: Attachment 330648 After the engine has been sitting overnight and is cold, let any fuel rail pressure off first by depressing the needle. Have a rag handy in case the fuel squirts out. Then remove the core needle from the fuel rail Schrader valve w. an extractor tool, same tool used for bicycle tires. Attachment 330649 My ever-present red-eyed helper: Attachment 330650 Screw the assembled gauge and adapter on the Schrader valve. Since it's a flare, do not use teflon tape, and do not over-tighten: Attachment 330651 Start 'er up and check for leaks. Hmmm, I'm about two PSI low: Attachment 330652 |
