FPR test?

Is there a way to test to see if it needs replacement?

Tee in a gauge with a hose long enough to tape the gauge to your windshield. Then go drive baby!

Hah really?

really, its what i did when i first turbo'd my SE and wanted to know what fuel pressure was under boost...i  now have a digital guage in my interior.

Whoa, going high tech! If I ever get a life, maybe I'll do that-makes good sense!

It makes sense I guess ill try it eventually

Generally, you pull off the vacuum hose. And it should run rich, and no fuel comes out of it. If fuel comes out of the vacuum hose, it's shot.

^^sounds like a better plan than taping a gauge to my windshield lol

Just depends if you want a dynamic test or just a go/no-go test. I originally got an ebay aftermarket fpr and it had a built in gauge. I pulled the gauge and put in a length of hose so I could actually drive and see what my fuel pressure did while in use. This is for testing only, I don't have a gauge duct-taped to my windshield as a mod if that is what you are thinking  :laugh:

Hah No that's not what I think but I just wanted to go or No go test. To make sure it works or not

Understood...driving it will give a good idea if it is delivering the right pressure for the amount of boost per the FSM. I find the the fpr are not very linear, the pressure just comes on like gangbusters when boost starts coming on.

But I has no boost :(

We T-off lines and tape/ziptie guages of all sorts to engines we test superchargers on to get pre/post install data.  Easy, simple and effective.  Also easy to restore to original.  You can find out all sorts of valuable quirky and unpublished information this way.

Yes, aviaition has a way of weeding out those who don't get anal about details. It takes a fair amount of external gauges to set fuel pressures up on those engines, and when there is an anomoly you really need good info to troubleshoot or just talk with the OEM.
