Measuring fuel pressure...

[Paul Workman]

Santa says not to buy a Helm's manual...(Gee. I wonder why he (she) said that???) Well, in the mean time, I want to measure fuel pressure and do a leak down test. So, some help, por favor! (I'll puruse the search function too.)

1. What would a recommendation be and where would I get a quality (not necessarily 'gold plated', if ya know what I mean) fuel pressure gauge, and where on the rail(s) do I connect it?
2. Do I need any special interface/connectors to do this?
3. What would the leak-down test procedure be, and what results would be "in the acceptance window"?

Thanks in advance.

There's a schraeder valve on the very end of the passenger side fuel rail.
It's got a metal cap that looks just like the cap on a tire.
You don't need the most expensive fuel pressure gauge, just go down to your local parts house and buy one of the middle of the line models.
Fuel pressure should be around 50psi and should hold for 10-20 minutes with the engine off.

Good luck!

I appreciate the info. Gonna head out and get one. (I suspect one injector may be leaking. We'll "ohm" it out and do a leak down test. Thanks for the help!)
