I ordered a Fuel pressure Regulator for my 2003 Jaguar XJR, part number JLM 21358 and returned it because it appeared to short to reach under the throttle body for installation. My Jaguar mechanic confirmed before taking the car apart. Please tell me what we are doing wrong. I have searched the forums and the internet and have found much conflicting information. Do you have a different part number for this application. Is there a piece that extends the FPR assembly to reach under the throttle body? Is there a How to guide that shows how to replace the Fuel Pressure regulator. Sorry I but have spent too many hours trying to figure this puzzle out. Please help. Thank you.

 

Hi zubizar,

I can see why you're having trouble finding the correct part!

Searching the part number you ordered, JLM21358, at jaguarclassiparts.com, reveals that this is the FPR for the normally-aspirated cars. Searching for an X308 XJR, the correct part number appears to be NCA5203EA.

Searching the Jaguar Electronic Parts Catalog (EPC), which you can download for free from this forum, returns the same results as jaguarclassicparts.com.

However, searching for NCA5203EA at jaguarmerriamparts.com and gaudinjaguarparts.com returns no results, and neither dealer lists an FPR for supercharged X308s. These are Jaguar dealers who sell OE parts online at discount prices.

Searching the Denso Part Finder (Find My Part | DENSO Auto Parts) returns no FPR.

Searching the main Bosch Part Finder (https://www.boschautoparts.com/auto) returns no FPR.

Searching the Australian Bosch Part finder (Fuel Injection - Bosch Auto Shop) returns fuel accumulators but no fuel pressure regulators. By any chance do any of the four fuel accumulators shown look like your FPR?

Searching the website for Coventry West returns no result. Searching the website for Jagbits returns no result.

Searching the website for forum sponsor SNG Barratt, the part number NCA5203EA is shown as having been superseded by NCA3007CA. Searching that part number results in an item called "PIPE - FUEL RE." I would suggest calling them to see if they can help. They're a sponsor of this forum and offer discounts to forum members.

Cheers,

Don

 

Part searches should always start off at jaguarclassicparts.com as they have the
most complete information regarding supersessions and fitment.

Part no. NCA5203EA | .Fuel pressure regulator parts from Jaguar Heritage Parts UK

click the little circular thingy for the supersession.

Don't see why it has to reach under the TB.

 

Where can I purchase part number NCA5203EA in the United States. Part no. NCA5203EA | .Fuel pressure regulator parts from Jaguar Heritage Parts UK, is the link to Jaguar Classic Parts and they say the "part is not available to buy".

 

Hi zubizar,

As I mentioned in my earlier post, SNG Barratt's website (sngbarratt.com) shows that part number NCA5203EA was superseded (replaced) by NCA3007CA, so that is the part number you need to order. You can try ordering it from SNG Barratt since they list it as available - mention that you are a member of Jaguar Forums and they may give you a discount.

If SNG Barratt can't get the part for you, try jaguarmerriamparts.com, the Jaguar dealer in Merriam, Kansas, who sells OE Jag parts at discount prices. Their website shows the part as available also (I've found several times that the parts exist in inventory in the Jaguar warehouse in New Jersey even when jaguarclassicparts.com says they are no longer available in the U.K.).

Cheers,

Don

 

Try Amazon. I buy most my parts from them. You should always start with them first for they usually have the best prices. See,


OR:

 

Part number NCA3007CA is listed as a "Fuel Pipe", not a fuel pressure regulator. This is a bit confusing and taxing on my Newbie brain.

 

Hi zubizar,

I agree that for some reason, some of the listings for the fuel pressure regulator for your car are confusing. Because of that, I would recommend you call the folks at jaguarmerriamparts.com, the Jaguar dealer in Merriam, Kansas who sell OE Jaguar parts online at discount prices. They'll be happy to help you find the correct part for your car. They have part NCA3007CA listed as a fuel pressure regulator and their discounted price on the original Jaguar part is only $8.00 more than the aftermarket part from the Amazon seller. For some reason it's not letting me link directly to the parts listing, so enter your car's year and model, then search for part NCA3007CA:

They cross reference the New Part Number as JLM21358. That is the wrong part number and I think it is for naturally aspirated engines. I have a call in to Barratt, they are "Looking into it". I don't want to pay a restocking fee for the wrong part. I will be doing fuel injectors also and I wish to tear the car apart only ONCE or it will get very expensive. I will post results.

 

It seems to be the regulator and pipe assembly which may be causing the confusion.
Part 6 below

 

You are correct I need Item number 14 on the diagram. That items is part number, NCA5203EA. Part number NCA3007CA is a "Pipe".

 

Hi zubizar,

Norri has solved the mystery! According to jaguarclassicparts.com, the parts service of the Jaguar Daimler Heritage Trust, part NCA3007CA is Part 6 in this diagram, which includes both the fuel return pipe and the fuel pressure regulator as an assembly:



See the full listing at this link:

Part no. NCA3007CA | Fuel return pipe parts from Jaguar Heritage Parts UK

I agree that the listings for the part you need are confusing and not all of the Jaguar parts listings show the proper supersessions.

Was the "They" who crossreferenced JLM21358 Jaguar, Merriam? If so, did you ask them to check the part numbers NCA5203EA and NCA3007CA?

I just searched RockAuto for an FPR for a 2003 XJR and they list a part from Airtex/Wells that is supposed to be equivalent to NCA5203EA and they show a photograph that looks like the pipe/FPR assembly shown in the Jaguar parts diagram. The Airtex/Wells part number is 5G1412, and Airtex happens to be an OEM to Ford, so if your original FPR wasn't made by Denso or Bosch, it's possible it was made by Airtex or another Ford supplier. You might have a look at RockAuto.

Cheers,

Don

Merriam references the JLM21358 incorrect part number

 

Hi zubizar,

I don't know if you just checked their website or called to speak with a parts rep, but sometimes the databases get corrupted. Try Gaudin Jaguar, the dealer in Las Vegas. They show the NCA3007CA as available:

PIPE-FUEL RETURN | Genuine Jaguar | NCA3007CA

It would still be prudent to speak with a parts rep to get his or her help in confirming the correct FPR for your car.

By the way, does the FPR and pipe in the parts diagram Norri and I have posted look like the pipe and FPR in your car?

Cheers,

Don

 

The FPR on my 2003 Jaguar XJR looks longer (the pipe) than the normally aspirated version of the FPR. I had a JLM21358 in my hand and it was obviously not the correct part (most people try to sell this as the correct part, NOT).


I appreciate all the help. Keep the info pouring in. I will Gaudin later, I have bought from them before.

 

Is there any information like a part number on your old FPR?

Could you take a couple of photos of the old FPR and post them here?

 

Keeping my fingers crossed. Picture of actual part attached, NCA3007CA.

 

... I came across this one while looking for an FPR for my '02 XJR-100, figuring that I would replace it while I had the SC off. I too ordered the NCA 3007 CA from Gaudin a couple of years ago. I took it to my local Jag dealer since I was having them do some work that I didn't want to do, and they didn't know what to do with it. They tried to remove the hard rubber hose from the old FPR, gave up, and told me that it was working fine. My original is stamped Denso 2901 96JV-9C968-EA which appears to be the same number as the NCA 3007 CA; but mine has a hard rubber hose that runs all the way under the intake elbow then connects to the return line behind the bank 2 head. So, I'm wondering how this one worked out for zubizar. I have attached a pic with the FPR still in place. (I tried to get a pic of the Denso part number but my camera wouldn't focus properly.)

2002 XJR-100

 

I posted the out of focus pic; here's the one of the whole part.

 

Hispeed42: I have the same hose/regulator in a 2000 XKR. I ordered NCA3007CA, the regulator looks to be the same but the hose does not fit! The hose is substantially different. AJ81480 is the original hose and regulator part # that is on our vehicles. The problem is it seems to be discontinued with no new part revision and it doesn't look like we can buy the fuel pressure regulator without the incorrect hose attached (NCA3007CA). At this point it looks like I'm going to have to fabricate the hose or order a used part.

Attached are photos of a brand new AJ81480 (now discontinued) part, so you can see what I mean.
