Correct way to remove and replace fuel rail

[jonbarrett]

Removed fuel rail to replace coils yesterday. What a dog to get off and on. Because the manifolds, injectors and rail make a triangle shape I had to apply lots of bending, twisting and forcing to get it back on. This does not seem right. Is there some sort of sequence or trick for getting the rail on with less force.

When replacing, is it best to put the injectors in the manifolds and then push the rail on, or put the injectors in the rail and push the whole assembly into the manifolds.

My fuel rail is just a grotty old piece of steel tube, not the nice machined ones I have seen on other cars. Are these machined ones a different design and maybe easier to remove/replace?

Finally, some of the o-rings were missing or damaged. Where is the best place to get new ones?

I find replacing the fuel rail with the injectors still attached to the rail easier and yes it doesn't feel right bending them against their will to get both sides in but it seem to work okay. Plenty of washing up liquid on the o rings seems to do the trick. O rings are from a Ford Scorpio I heard so any main dealer should have them.

I know what you mean.

However, I find it quietly reassuring that these cars are really nuts, bolts and a bit of steel and plastic etc and that they are not like the hi tech computer controlled engines you find in the upper end of the luxury market - and they can still whack out 450bhp+.

I did mine a few months back, to fit new oil pressure switch (under coil packs.

Yes, you do have to manipulate the rail quite a bit to get the injectors back in properly.
Yes, as stated, the o rings are from a Granada Scorpio, Ford dealer. Not dear so replace them all if you can. And lube them before attempting to push them back into place.

If its any help, I took mine out and put them back with the injectors in the fuel rail. Next time I might try it the other way to see if its easier or not.

on my 4.5 the o rings were from a peugot and about £60 ( I didnt think that was cheap)the old rings had swelled up and it was much much easier to fit with new rings.

£60.00 for 8 pieces of rubber?

yes it is expensive but in my defence it was 16 pieces of rubber (I changed them top and bottom)
