Square fuel rail original look?
Hey there,
I'm still getting stuff all ready here and having more and more parts galvanized to look good again.
The original square tubed fuel rail (the "common rail") on my car was well aged... No shine, all crud. I rubbed the crud off, but it will of course change colour again as soon as the car runs...
What was the original finish? Was it silvery and shiney or always a matte look? Was it maybe even yellowey galvanised?
Cheers
Damien

We had a place in St Louis that plated our stuff in 1990s, closed down because of emissions. Silver cadmium and we also did the gold. Eastwood sells a cad spray for carbs that does not peal or turn color. Small aerosol cans, works great if metal is prepped and the spray allowed to dry.

its fine sterling silver.
Step 4. Polishing. There are a lot of metal parts that can be shined up nicely, if you want to take the time and trouble. Notice all those dull gold-colored pipes, including the fuel rails, throttle linkage, intake manifold and crossover pipes and miscellaneous water and emission pipes? They are actually "fine sterling silver", waiting to be discovered, and can look like chrome if you are VERY PATIENT and have the right equipment!

Yep those black pieces are original. Never figured out what they are for. I took them off years ago to polish my fuel rail.
Looks like your rubber parts are a bit haggard. I'd suggest replacing the fuel rail hoses. It's an easy, but slightly time consuming, self help job. Engine fires are a common theme. I'd also replace the dual coil with a modern higher capacity single unit if it hasn't already been done. The second coil is in front of the radiator. Just follow the wire.
If it is a Lucas ignition car pop the distro cap off (mark the plug wires first) to check your centrifugal advance to make sure it is "springy" and get several drops or just a bit more good grade engine oil down the center of the shaft on the wadding.

Leo,
I see from your picture above that your car has the non-air injection tube plugs. US cars had a mandatory emissions air injection system back in the those days. An air pump forced fresh air into a air rail that had tubes feeding down the exhaust manifolds to reduce the emissions concentration. On US cars these plugs have a hole for the tube to fit down thru. I'd much prefer to go with a factory still piece than fabricate a home solution.
Any chance you or another European mate could pull a set of those plugs off a scrap yard car for me. I don't want to spend the $130 or more as listed for a set from a company in England that Greg? identified previously. I'll also need the idler pulley.
Yes, I am cheap. I also have an ex-wife I am still dealing with. The math matters. LOL

I think the cars without the air injection were simply fitted with undrilled manifolds. I think what you see in Leo's pic is that undrilled boss.

Yes, the undrilled boss or plug. It is sort of ""kidney" shaped that has a bolt coming up thru it held by a nut. In the picture you can see one of the 12 below the throttle kick down switch.
As far as I can tell there would be no need for these on euro cars if they were not drilled for the air pipes.
I'm certainly no expert on the differences between the euro motors and the US versions. Expert opinion is appreciated. If these won't work for whatever reason I'll have to bite the bullet and get them from the company Greg listed.

I did not check the forum on it yet, as I am simply not that far, but now we are at it, and Daim was already answered, can the air injection just be removed and capped on a US car?
I have no emission issues over here for the XJS.

An other one to investigate before assembly.

There is no plug or whatever on a non air injected motor. The aluminium is just not drilled. What you see in the pic is the aluminium boss, not a blanking plate. Another clue is the excess thread visible on the manifold stud. My XJRS is UK spec without air injection and no holes in manifold, no need for blanking plates.

I think you misunderstood my post Brad.

I have the new type coil ready, and will be be mounted before winter season is over.
Actually the second coil is currently missing, I guess some smart mechanic has decided it wasn't necesarry...
I have been inside the distributor and checked that the advance is free too move, but I didn't lubricate. I have since then bought new rotor and distributor cover and will do it while I'm changing these parts.

Spares are rare and expensive in Denmark, so I suggest you get some of the Englishmen to source spares. Andy from JustXJS should be able to help you if noone else chimes in here.
