Whats the point of the fpr shim?

Would it be beneficial on my '97?

Measure you current fuel pressure at idle. You want it at about 65 psi. Cheers!

Gives better/more pressure and more consistant as you keep on the throttle.

Where is the schrader valve on these?

Is this actually noticeable in hp/delivery/mpg/throttle response etc?

Shrader valve is on the side of the fpr.

You'll only notice a difference if your fuel pressure is to low.

Ah ok. Good deal. Where do I get the shim from and where does it go? Between the fpr and the bowl?

[Patrick Feeley]

The "shim" is either a BB or a 4-40 socket-head cap screw. It goes between the valve spool and the spring in the FPR. You remove the big hex plug on the FPR and remove the spring and spool. Put in the BB or SHCS (threads into the spring in that case) into the spool's spring bore and reassemble the FPR. Alternatively, you can get the regulator "kit" from Ford made for the late California trucks. It repalces the spool, spring and plug with new parts and does essentially the same thing. The part number is:

Fuel Pressure Regulator Kit (contains spring, valve spool & new brass plug)
(Ford) F6TZ-9K061-AA (CA emissions)

Cheers!

How much does the kit go for? Is this pretty easy to install?

^Freeley, if that was a link it didn't work.

Its not its just how he posts Ford/ International part-numbers.
