Fuel rail replacement - methods?

[fenderbender]

About to replace my fuel rail after partial dismantling to fix wiring loom short.

Whats the general consensus for best method? Is it to fit the injectors into the rail first then locate the whole lot back into the manifold before bolting down.... or is it better to leave the injectors in the engine and try to tease each one back into the fuel rail?

As removing it caused physical injury (blood everywhere...!!) I'd rather do this the easy way!

Hi Just replaced mine yesterday found it best to put injectors
in fuel rail first clip them in and then put on engine remember
to put a film of oil on o rings to eases entry ooo eeer

I prefer to clip them into the rail first as this locks them at the correct height and saves some messing around, but do it however you want.

Excellent. That's two votes for method A, so the "A's have it" !

Thanks guys - I'll give it a go, but I have to say that the rail itself seems to be about the most rigid piece of steel piping I've seen outside a scaffolding depot. Does not seem to have any flex at all...

I did the same method with mine as well.It's worth mentioning to have a good sized rag or somesuch to hand,ready for when you put pressure back in the rail,then if you are unfortunate enough to have a leak you can quickly deal with the fuel spray.

Excellent advice, thanks. I'd better turn off the 500W mains operated halogen floodlight too. Its currently sitting on top of the coil!!

Just another thought - there is no gasket between the plenum chamber cover and trumpet base, or between the trumpet base and the inlet manifold. I expect a very thin layer of not-hardening instant gasket will provide an appropriate seal. Any other thoughts on this?

I also add a little vaseline to the injectors rubbers to help them slip in more easily without any issues later down the line.

Heps them eal and fit in and I go with Option A, although I do not add the clips until the whole assembly is in situ .. ..

I use a little blue hylomar to seal the plenum mating faces. However, just make sure that it is a very thin layer so that when you torque up the bolts the excess does not squeeze out and potentially end up getting sucked into the engine. Vaseline works well for lubricating the injector seals.

I just took off my injector rail and injectors and would definately recommend putting the injectors into the rail - then fitting the rail and injectors into the inlet manifold.

Me to, damaged an O ring doing it the other way, £2.60 each from Rimmer Brothers!
