I thought the S3 (and later S2) cars had submerged pumps. What is the donor car, 4.2, V12 ?

Different to what, an earlier S3? Could it be the wiring for either the in tank fuel pumps or the changeover system?

I looked at them a while back while searching for a set of budget 205 70 15 as a stop gap to replace ancient Pirellis, something put me off but I can't think what. I ended up buying Goodride's which had decent reviews and performance ratings and put them on Kent alloys but haven't used them yet.

In researching the model I found a great channel called Living With A Classic including a 4.2 head stripdown carb tuning and other well shot and informative stuff including insight into the long stud version. Mostly based on an S2 that appears to have a later engine with the lateral cooling passages...

A couple of years back I had an XJ-S V12 rad re-cored by Bryan and Son in High Brooms near Tunbridge Wells 01892 544635. Very old school place that gets lots of vintage and veteran work. Can't remember what I paid it was around £150-£200 I think. He also brazed my XJ6 expansion pipe when I broke it ...

Hi Mike, yes maybe I have got long stud paranoia, and I had thought about a compression test. But I've got some new improved cam cover gaskets and new O rings so I might as well fit them and see if that makes a difference. I've already replaced the oil feed pipe washers. Maybe I'm not seeing a leak ...

Having chased down some leaks from the cam cover gaskets I thought I'd got them all but as we've got into winter I now have one that manifests itself when the engine cools down. It seems to be coming from the exhaust side of the head gasket between cylinders 1 and 2, runs down the side of the block ...

The bush is probably CAC3227. Not sure about the spring as I think they might differ between 4.2 and 5.3. I just changed the bush (on my manual car) and did it with the car on ramps using an axle stand to support the box and a trolley jack to take the strain while I undid the bolts. I also needed th...

This is all I can find, for the S3 (auto presumably), and it isn't in stock

1972 S1 manual. I noticed some sponge like material between the front of the gearbox and the transmission tunnel where it meets the bulkhead. Is it a bodge to stop knocking as a result of a worn rear mounting (now fixed), or is it meant to be present? In trying to research this I found a diagram for...

From the Burlen website:

Part Number: AZX 1308
Description: HP Electric Fuel Pump - Dual Polarity

I'm told that the only polarity specific pumps they now make are the electronic ones which are AZX 1308EP and EN respectively.

Hi Alec according to Burlen the AZX1308 is dual polarity. The CZX2004 they inform me is a dual polarity diode whose function is to limit arcing between the points, and is connected between the points arm and the earth side of the points. Burlen suggested I disconnected the diode to see if the pump r...

I've replaced the tanks and cleaned up the fuel system. To get the car running I put a few litres in the RH tank until I could hear bubbling when I blew up the pipe on the inlet side and reconnected the RH pump . Nothing, looks like the pump electrics failed (points burned and springs not closing th...

Yes, one rubber bush was missing so I replaced that. Fortunately the mounting brackets were ok.

Hi Mike I found that using an old fashioned exhaust clamp rather than one of the theoretically better single bolt types worked better on those joints. Still a bit worried about all that weight hanging off one downward facing joint.
