You can change your fuel pressure regulator to the Exergy replacement. This will not save the CP4 but will save the rest of your fuel delivery system should the CP4 grenade. Around $260 + labor. This may leave you in the middle of nowhere suddenly should the CP4 go, but the repair cost will be about $10,000 less than it would have been without.

Lastly you can change your CP4 to a CP3. Here is a thread that is about that conversion. Quite frankly if I had an LML, I would have already done this.

Take your time, read and research all the above and decide what solution is best for you.

And finally, a bit of help you did not ask for. This thread may interest you as well.

Thanks for the information. I've ordered Opti-lube XL to add lubricity. Before my warranty expires, I'll have to decide on next step.

You were in the right section. It's not a really big deal. It just is more appropriate to start your own thread rather than use someone else's. The other person might want to continue on with a couple of questions or something like that and by diluting his thread with your own intro it takes away the focus from him. It happens a lot. Not everyone who is new here has had other forum experience so etiquette is often ignored.

I hope you are not offended. You are welcome here.
