2003 Jaguar Fuel Pressure Regulator
#21
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).
The parts catalogue shows:
where the top pair is up to VIN 835511 and the bottom pair for VIN from 835512 onward. It appears that, for VIN up to 83551, the pipe NCC3007AD (short) and the FPR NCA5203EA were initially available separately but later "merged" into one assembly under NCC3007AD (NCC3007AD plus NCA5203E). This appears to be the reason why, if you try to order NCA5203EA, you are directed to NCC3007AD which now represents the whole assembly.
For VIN from 835512 on, the parts catalogue shows that the pipe and FPR are sold as a set (the square bracket at the right in the catalogue) under AJ81480 and shows that this set has an FPR NCA5203EA, i.e. the same FPR as on cars with VIN up to 835511. The problem is that, if when ordering the FPR for your VIN 835512 and later, you use p/n NCA5203EA shown in the catalogue, you are directed to the whole assembly in supersession for the earlier VIN-s (up to 835511) and not told that, in the case of VIN from 835512 and later, you should go for the set AJ8148 (FPR plus a long pipe).
AJ8148 appears to be available from Barratt at GBP 97.24.

I did see the same thing when viewing the sng barratt website but when I contacted them yesterday via phone, they informed me they have none in stock and that it is discontinued so they cannot order it. They recommended a used part or fabricating a replacement.

seawind - thanks for the reply. It looks like we're finding the same thing as we search for a replacement FPR. My original is still working fine, but with 173k miles on the thing, it's sure to give up sooner than later. So, I'll get another NCA3007CA, or whatever part number of the day, and be ready to do some modifications. I wonder what glue they used to attach the rigid hose in the original part? That stuff really works !!

I don't believe it's glue, the short hose on nca3007ca seems to be on there tight as well but it will fully rotate around the regulator nipple. I think the interior of the hose is made out of some kind of plastic and after time it just gets welded to the regulator which makes it seem like it's glued. The regulators for the supercharged engines can be purchased for about $130, that is exactly what this regulator ahould cost but we have to pay $70 for a hose we can't use lol. I'll probably get some fuel line, remove the new hose, and hook it all back up today.

I don't believe it's glue, either; that was a little sarcasm as the dealer that I tried to get to install the short hose FPR (NCA3007CA) gave up when they couldn't get the hose off of the original FPR. It will be interesting to get out the Dremel and start cutting on that hose when the time comes ...
Has anyone tried to fit the short hose FPR to see where the pipe ends up when everything is in place? That tang on the pipe is supposed to bolt somewhere, then the return pipe/hose would snap-on to the FPR pipe. Would it be easier to cut the pipe on the short hose FPR and fit a hose to the return pipe using the nipple from the original (AJ81840)? Or, as M. Stojanovic suggests, cut off the hose at the FPR and run some fuel line over to the return pipe. Either way, I would be concerned with using clips or clamps to fit the hose, as it could easily slide off the pipes under pressure without some sort of a collar or a compression fitting with a hose barb.
