Can someone tell me if this looks like Jaguar fuel pump? I can't tell the model number on it and not sure where to find replacement for it.
I remember I bought ignition parts from online store in Michigan but lost my bookmark to it. Anyone knows their URL or can recommend other N. American shops with parts for old jaguars.
People commonly fit the electronic models now, not those with points. The old type were the ones that used to give the "tick, tick, tick" when you switched on the ignition. You can still buy these : -
Hmmm.
Hardy pump; there was a post with a guy who owned a Porsche where the thing failed and left him stranded.
Yeah I know, a once in a life time fluke _ right...
I honestly have never had an SU pump fail, and if they do fail, it's usually because someone who rebuilt it, didn't know what they were doing.
No that guy with a (hired?) Porsche probably had a flooded Pierburg or Bosch pump where rust particles in the fuel collect on the pump magnets until it seizes. I remember that post.
I'm from a long career in the petroleum industry & we globally & collectively have a good broad idea of fuel pump reliability. SU does not rate high on the list. Hardi pumps on the other hand are particularly reliable.
One of the few breaks from originality I made when restoring my car. They are a direct drop in, make the right noises & you can't see them under the covers.

What did they say that was so terrible about the SU fuel pumps ?
I find people complain about things when they break down when it hasn't been serviced for 50 years and the SU fuel pump is a good example of that.
Or they try to repair or rebuild it and they have no idea how to set it up, and they blame the design.
I went to this Jaguar show in Victoria just a little while a go and I was casually chatting with some of the owners and I was amazed how many of them had no idea how to really set up their carburetors.
Some knew a little bit, but not enough to comprehend how they worked or to adjust things properly.
And I believe it's that sort of thing where things get a bad name from.

Issues over the years have related to just about everything from diaphragms, to valves to burnt electronic boards to the well know point issues on earlier models.
I guess it is why SU ceased to be an OE supplier to the automotive industry & thanks to Burlen only supply for legacy vehicles still on the road.
Jeff evidently you and I are the only folks on the planet that have no issue with SU pumps! Good on us!
Apparently.
My Dad bought a 1963 3 litre P5 Rover and it was driven into the ground, but all the years we had it, the pump never gave any problems.
Same with an old Mini we had.
And Glyn, what electronic boards, all the pumps that I've had had no electronics, just a condenser to keep the points from burning ?
Go to Burlen website or Fraser Mitchell's post above for example
Another nice thing about the Hardi pumps is that they are not polarity sensitive.
Neither are the SU pumps if the polarity sensitive capacitor is replaced with a varistor.
And I believe some capacitors are not polarity sensitive.
Sorry to be argumentative, but taking something as simple as a pump and making it more complicated by adding electronics seems a step backwards.
I'll argue that as well to my grave when it comes to all these questionable aftermarket electronic ignitions, I've had nothing but problems with those.
And yeah I know, this subject has been beaten to death elsewhere.

I know the varistor trick but once again why did SU not design it that way. Most of their issues have been QC related.
I live in the modern era & embrace technology. Imagine driving a modern car without fuel injection.
Anyway ~ people should do exactly as they wish. It's their car. I was merely pointing out that there are good alternatives.
Yes, I can imagine driving a car with out modern fuel injection.
It would be great !
The whole system works very well when it does work, but things get old, it can become very complex to diagnose and repair properly.
The computer may throw up a code that may mean there's too much oxygen in the exhaust, so one has to find an experienced mechanic to know that doesn't necessarily mean that one of the oxygen sensors is faulty.
The auto pats store says, "yup, that's broke" and one spends money and it still doesn't solve the problem.
It's never that simple.
While the above problem may be an over simplified problem indicating a faulty injector and or a clogged fuel filter, or the beginning of a failing fuel pump, the whole thing is overly complex to control what has become a very antiquated way of getting around using an internal combustion engine.
I do embrace technology when it makes sense, it doesn't make sense to add electronics to an old design that's been around for more then 100 years.
The combustion engine generates too much heat and carbon for the electronics to accurately read things over a long period of time.
Things get clogged up with carbon and fail from too much heat.
I'm old school too and I don't mind fuel injection when it works, but trouble shooting it, even with experience and the right tools can be a challenge !
Even now my daily driver, a 1999 Mazda B3000 truck is experiencing an annoying problem which I can't figure out, it drives and runs great with good power _ doesn't knock or ping, but it acts like it has a small vacuum leak somewhere.
The idle is not rock solid as it should be for an injected vehicle, it wonders around from 800 to 950 rpm and when just coasting along, I can feel this variation while driving.
I've been through it many times testing for vacuum leaks and even did a smoke test on it and of course nothing faulty was found that fixes the problem.
I did find numerous things that were not right, like some idiot put the cam shaft sensor in wrong, the DPFE sensor circuit board in the EGR system was totally rotted out.
There were meany other things that just needed maintenance and each thing that I did improved the original rpm problem, but it's still there.
That's why I don't like fuel injection, I've spent countless hours trouble shooting and reading about things and learned a lot, but not enough to fix the rpm problem, so give me a carburetor any day of the week !
I do know someone quite well that would more then likely discover what's wrong, but I'm too cheap to spend the money right now.
And that in itself is a PITA, I have to leave it at the shop he can start it when it's cold and see what's happening in an open loop.
That requires dropping it off and getting a ride home or take the bus _ I'm 1/2 hour away from the garage _ very annoying.
It would be the first time in my life that I would pay someone to fix my vehicle !

We will agree to differ. I don't understand all the passion over a crappy, flawed & obsolete fuel pump. Regards the rest we live in different worlds so discussion is pointless. I am certainly not old school and have no desire to be. Getting on in years ~ yes. I love what modern electronics have made possible in cars. Multiway communication between all modules over CANBus Networks, proper engine & transmission management etc. etc. ad infinitum. Everything properly integrated & efficient. Drastic reduction in point to point wiring & super reliable. Simple diagnosis with an OBDII scanner that costs a few bucks. Huge reduction in emissions. Drastically enhanced safety due to on-board systems.

For the record, the modern SU electronic pump, which looks identical to the original points pump and is a straight, no issue replacement, still ticks like the original and works perfectly.
And Jeff, I did not see you at Jaguars-on-the-Island, but you might have seen my Pale Primrose Mk 2?

I looked for you, I wasn't sure what car you had, but obviously I missed you, maybe next year.
I wasn't going to go, the it was a last minute decision.
