As almost a log-termer, I have read the various fuel pump replacement threads over the years.
I noticed that there seem to be 1 or 2 replacements brands which are doing well, and some others which do not.
Also noticed a variety of prices mentioned.

Now, helping out a friend, I tried to find that particular info, but so far I came up empty handed on the good and bad.

- Uro
- Denso
- Airtex
- Delphi

Can some of you done this job throw me some of your impression of them on fit and durability?

Cars involved are 1998 and 2001 XJR and Daimler Super Eight.

Much appreciated!

Eric

 

I changed both of mine last year for the Airtex units. They're a well known manufacturer that cover the OEM arena and field service replacements. Very cost effective. No real problems fitting- needed to fit a pig tail connector to fit and minor 'clamp' amendments.


Have driven the car about 4000 miles since and its been about a year with no problems.


In retrospect I wish I'd gone for an upgraded output fuel pump, like the ones available in light of my intended future mods.
However they've been absolutely fine in daily use operation so far

 

Thanks, it is new material for me, and these are not my cars, so don't want to spoil the friendship by some bad advice.

As we will need to buy from overseas, will a set like this DENSO kit cover all parts needed (besides of the fuel filter replacement)?

 

I used that denso kit and it included all the parts needed for the job

 

That is as clear as it can be, thanks to both of you.

 

I swore off buying products from Airtex after a few defective parts. Installed one of their fuel pumps once (not on a Jaguar tho), then immediately took off on a cross country trip. Pump failed about 900 miles from home. They were nice on the phone and got me a replacement pump within two days. Thought all was OK. Then that pump failed on the return trip. Both the same manufacturing defect, a small crack in the casing. Airtex was nice again on the phone and arranged a refund but they didn't cover the four extra nights in a hotel waiting on parts shipments or the tow truck charges. I replaced it a second time with a Bosche unit instead. Many years later I forgave them, thinking it was just a one-time bad batch and bought an Airtex water pump (for the XJ8) based on recommendations on this forum. Nope. It sprung a leak within a month and nearly overheated (pulled over after seeing steam), again on a trip hundreds of miles from home. I'd probably choose the Denso fuel pump if I were doing this repair today.

 

I found 2 Delphi's on ebay for $45 each and grabbed them. They've been in place for 3 years now and almost 10k miles (the cat gets put away for winters here). They were fine but needed to have the old connectors spliced onto them. Not a big deal but I needed to source fuel resistant heat stink tubing to cover the solder joints. I know people think crimp connectors are better than solder but I couldn't find any recommendations for the proper crimp tool and I know my handyman special is close but not the same as a proper tool for this job. I'm much more confident in my soldering abilities.

 

What's wrong with OE? I see some independent Jaguar parts specialists offering the real thing at right money, no in tank loom hacks or bracket alterations. The brackets are oval, fitting a round pump with give uneven pressure on the casing and possible failure....plug and play all day on these things for me.

 

Sean, I do fully agree with you on the technical argument.
However, you might be in the good old England, but a lot of us are not, changing the playfield:

- First, Jaguar does not make fuel pumps, but just buy them from a supplier as well, branded or unbranded.

- Second, buying in the UK, or EU, it means extra shipping, that's sometimes OK, other times a rip-off.

- Third, it means exchange rates and it differences.
SNG for example has big differences in their pricing in-house, where their parts on the US website are up to 30% different than their UK prices.
I can understand that this happens with the hostile rates of the last year, but it also means other suppliers might take it different and are way cheaper.

- Fourth, being in Taiwan (and I am sure it is the same in a lot of other countries), companies like Jaguar seem to be not at all interested in part sales, and if they do, they are tripling (!) prices.
And that is not only shipping and duties, believe me!

- Fifth, a site like Jaguarclassicparts does not mention any brand, where on a site like Rockauto I have all brands listed, and make up my own mind on brand and the price I want to pay.

I am not a scapegoat, and generally prefer to buy the best parts for my cars, but don't get satisfaction from paying double the price for the exact same product (remember the Bilstein shocks we discussed before).

 

Thanks.
As mentioned, these are for a Taiwanese friend here who has a garage full of x308's (all Daimler Super Eight's and XJR's besides of some x300's).

It also means he is probably up quite a bill, as his intention is to do a preventive change, and shopping around will make double sense for him.

Anyway, I will see him on Thursday to pick up a car with some power problems, and will see what he wants.
Thanks for all input, it helped.

 

I agree with both Sean & Eric. I'd love a plug and play solution and am willing to spend a little more to have that. When I did my pump change(s) the Jaguar versions were going to run me $200 more each than the Delphi versions I found so I broke out the soldering iron.
I don't think any OEM's make motors (or pumps with motors) so outside of the connector issue I don't see a downside to not using OEM. In this case these are the 1st fuel pumps I've ever replaced (I did one in my Caddy but the pump was fine, I was sick of not having the gauge work, which is part of the same assy, which still had soldering to do because the "OEM" design had been updated) in any car I've ever owned so for that reason alone I'd steer away from what ever company Jaguar sourced their stock pumps from. I'm still kind of surprised that we need 2 pumps to feed a 370 hp motor in the first place but that will all fade from my feeble mind as long as I don't have to do this job again. Now if I could only say the same thing about my driver's door cable...

 

Interesting... My brother's XJ8 just blew it's fuel pump, so I think (149,000 miles). I'm in the USA. Can someone tell me where is the best place to get an OEM pump and what would be a good option so my brother can decide?

 

I installed 2 Airtex pumps a couple years ago - no problems
