Re: Which Ignition

In my opinion the pertronix 9lu-1122 a (Please note the "a" at the end of the part no is MOST important) is a very cost effective and elegant solution for the V12 now. Have not used it myself though. I would recommend this upgrade be implemented with the vacuum advance module JLM519 on the dissy con...

Re: Fuel gauge not registering properly

Dear All, Just seen this from 2010, "You can then use your meter to measure the output voltage and thus deduce the on:off ratio. To change that ratio (and thus the average output voltage), you'll need to adjust the adjustment screw in the base of the unit." So the instrument voltage regulator can b...

65 wire wheels tubeless?

Would the wire wheels of 65 S1 XKE be tubeless or require tubes?

I ve also done a small hole into the tank cap to avoid the fuel smell.
We both should now close that hole in the fuel cap as there no need for it.

I think you have? A filler cap that vents to atmosphere and an expansion tank that vents to atmosphere?
Correct on both accounts. Should I block the vent in the cap perhaps?

Re: S3 Fuel Expansion Tank

Are you following the "A" and "B" nomenclature from the S3 schematic in post #23? Yep. If so then it looks as if your "C" and the "A/B with a horizontal arrow" are the wrong way round and the expansion tank won't drain back to the main tank. It doesn't matter which of the the two outboard connectio...

Re: S3 Fuel Expansion Tank

I went and had another good look and I found all 4 of them breather pipes. Just extremely hard to see. I applied compressed air (at about 0.2 bar) to the vent pipe and could hear air being blown into the tank (which is near empty) and out of the small hole in the fuel cap. The two pipes are labelled...

Re: S3 Fuel Expansion Tank

Thank you Bob! It WOULD make sense for '71 S3s (mine is Oct 71) to have a rather similar setup as for S2. Its MUCH harder to see what is going on ito breather pipes on the Oct 71 FHC than what it is on the Dec 73 OTS. I'm going to have another look.... It seems the physical locations of the breather...

Re: S3 Fuel Expansion Tank

So unless the filler cap has been replaced by the vented type, whenever the main tank level is above a certain level (vent/return C being the lowest of the 3 standard vents) either by fill level, parking nose down or braking there is no venting of the main tank. The cap is a vented one. Has a small...

Re: S3 Fuel Expansion Tank

So, I brought my '71 FHC home in the hope of finding an expansion tank related pipe being the cause of the petrol fumes in the car. Surprise!!! The '71 FHC fuel tank has one got the "expansion tank drain pipe" labelled "C" in Bob's drawings. No A and dB barbs. The expansion tank also has only two pi...

Or are non emission fuel tanks sealed, i.e. remove the filler cap on a hot day, is there a purge of pressurised air?
I've never had this but now I understand why. There can not be pressure in the tank with this breather.

Re: S3 Fuel Expansion Tank

I plan to get rid of the expansion tank and just have one small breather coming out of the top of the fuel filler tube and then down through the rear floor at the same point as the water drain from the boot/trunk lip. P Don't. If you fill the tank and then park the car leaning downhill to the left,...

Re: S3 Fuel Expansion Tank

Surely this would make the car incredibly smelly? Phil, is this correct, your tank is openly ventilated by this hose? The pipe comes from the expansion tank, goes through the body to the IRS cave and terminates there with an open pipe. But this open pipe may not be how it came from factory - this c...

If anyone can help, I would still like to bottom out the issue of where the expansion tank vent pipe on a non USA/Canada car exits the bodywork.
This is on my S3 RHD OTS:

A close examination of the case/end cap will reveal a small line mark made by Lucas. That line is for correct orientation of the body/cap relationship.
Spot on Dick!!! Aligning the two marks result in the fan turning the correct.

Re: S3 Fuel Expansion Tank

Fantastic pics, thanks Bob! Now comes the big question: Which connections on the tank goes to which connections on the expansion tank? I am aware of three connections on the tank but I see 4 connections on the expansion tank. I presume one of them would go to the carbon cannister or otherwise atmosp...
