Okay, I know this has been discussed before, but I'm lazy alright!

I believe that I have a bad press. regulator. My fuel pressure gauge jumps like a kangaroo after a few minutes of running.

Pendy wants me to test it, by crimping the return line and seeing if the pressure climbs and stabilizes, but I like keeping him frustrated by not trying that approach. I, like many Land Rover techs, prefer to toss out perfectly good parts for new expensive good parts. Much less thought involved!

Seriously, I haven't had a chance to run that test yet, but I'm 99% certain that's were my problems are as that thing is over 14 years old now.

Question: Who has the best price on those sucka's. I've heard that they are akin' to a control module in price. Any sources on used?

Will Tillary should have one used.

Doug:
Would you like me to send you one to try?

I picked up a couple adjustable regulators from RPI a few years ago that worked great. I've been planning on ordering a few more. I'll check on the price. Let me know if your interested and I'll put your name on one.

I got about twenty used regs. You can have one of those for free if you want one.

I would've thought any FPR designed for a similar setup would work, the universal adjustable "performance" ones are common enough and will do the trick if the genuine bits are pricey.

WOW guy's thanks!

Silver S., If you can part with a use one that would be awesome. Also, a price check on the RPI adjustables would be awesome.

Thanks for the offer PT, but looks like two birds with one stone here.

I like the idea of going with an aftermarket part. If I was to do this would I remove the old, and find a cap of some sort to seal up the rail? Or could I remove the diaphram in the old and keep it in place? What about the vacume line?

Sorry for all the questions, but in 14 years I've never had to deal with this one.

Done.

They supply a adaptor to fit in place of the original reg and then you mount the new reg nearby on the fire wall or wherever you have room. Also comes with a braided vacuum line. They list for 85 pounds but I'm not sure what the exchange rate is latley. I'll check on it get back with you.

Cool, beats having to braze a fitting on the fuel rail like we're probably gonna have to do with AFI's truggy.

Is this adapter available separately?

Done.

I'll check on it get back with you.

Thanks a million! I'll let you all know how it turns out.

Doug:
Other than the fuel pressure fluctuations, how does the engine run? How much fluctuation are you seeing? 5-10 psi or 10-20+ psi?

PT

PT,

She runs perfect...Until the pressure starts to jump. Nominally 10psi jumps up/down about as fast as the needle can move. Makes me think that there is air in the line and/or the fuel is boiling. The later I find less likely because I ran the fuel lines down the center of the chassis, away from anything hot.

Anyway many thanks to PPR's for the fuel regulator! I'll let you all know what happens.

Doug, it would be illustrative to crimp the return line, at least partially.

I wonder what is happening to the fuel pump, current draw, etc. when this begins to happen.

Yes you and Pendy are saying the same thing. Thing is that the pump is proven in the last iteration (rock-90), doesn't leak, builds presure intitally well, etc. If the regulator doesn't cure the problem I will try a different pump. I'll keep ya' posted.

I'm curious to find what the resolution is. Seems as though we've had a spate of fuel pressure regulator issues of late.

Given the fact that this is for all intents and purposes, a new vehicle, there are things that may have changed we're unaware of and may remain that way for some time until something happens to reveal what's going on. I've had fuel pumps confuse the daylights out of me.
