Not much to it really. 2 bolts holding it to the manifold, pull off the vacuum line and disconnect the fuel supply and return.
Suggest you disconnect the battery first as the system primes itself to ensure there's sufficient pressure for when you start the car. You don't want it priming and spurting fuel whilst you've got the lines off - you don't want faded paint and a knackered alternator not that I'd now anything about that Whistle

Grab yourself some new O-rings from Mr Injector as the old one's will probably be past their best, bit of rubber grease helps them go back in to the manifold too.


Also, the fuel pressure regulator probably won't come out cleanly if you choose to remove it to paint the rail - factor in a new one if you do decide to pull it out.

They're filter baskets for the injectors, could do those whilst you're at it.

A garage changed my starter motor and misaligned the fuel rail while re-assembling and bent the fuel rail causing a bad fuel leak so make sure you line the injectors up correctly before bolting down.

Do you have a part no for the seals?

Also do you know what spec the FPR seals are? Mines been removed for powder coating the rail, and the seals on it are ruined.

I think it was these one's

As for the FPR seals, no idea but probably nothing special - just a nitrile rubber. If you're ordering injector seals maybe ask Mr Injector? Must have something in the right size for petrol application?

Why would they have needed to remove the rail from the manifold to do that? You would just remove the manifold complete.

They thought injector 1 was slightly weeping.
