I am in the process of replacing the valley hoses and securing all the gaskets and O-rings. I have a couple questions I would like some help on if someone has the answers it would be greatly appreciated. I searched older threads but did not find anything relevant.

1) There are 16 injector O-rings that I have priced them and the best I can do is about $130.00. Is there a Ford/Lincoln matching part number for less?

2) There are throttle body gasket and induction elbow seal are these available as a Ford/Lincoln part?

3) A multitude of O-rings for fuel pipe, fuel cross over and fuel Pressure regulator. Anyone have Ford/Lincoln numbers for these?

 

I replaced my intake manifold and used the same “O” rings and gaskets just used a good quality silicone lube. You know that you can have your injectors rebuilt. This is a link on what I did.

For about the same price as the o-rings you're sourcing, you can get a high-quality ultrasonic cleaning of your injectors, pre and post flow-testing, AND all new o-rings.

The vendor is Injector RX in Houston. A great service. I used them two years ago, and was very happy with the results.

You can find my thread on that service HERE. Good luck.

What year and model car? For my 2001 XKR Rock Auto has the injector orings for $2.94 per injector.

 

There is an ebay supplier that sells a complete injector o-ring kit for your car, including replacement strainers for about $33. See V8 4 0L Jaguar Fuel Injector Service Repair Kit O Rings Seals Filters | eBay

 

1999 XK8 but the motor is a 2003 replaced by the dealer under warranty

 

If you order the ebay kit, make sure you then get the 4.2L version!

 

You can clean your own injectors very good.

I remove the injectors,so the engine will not hydro lock.

Place a rubber hose on the injector end.

Fill the hose up with fuel injector cleaner.

Blow on the hose,while using a battery and wire setup,to pulse the injector,until all the PURE cleaner is gone out the hose.

Works every time.

 

you have to put silicon on the orings before you put it all back together? What kind of silicon?

 

A good quality silicone.

 

For those of us in the UK an outfit called polymax can supply appropriate O rings. Probably somewhere in the the US too.
Anyone able to put together a list of O ring sizes?
