I am removing the head off my S2 tonight, my problem is when i remove the fuel lines from the back of the head will it empty everything including whats in the tank(i have a full tank of petrol), or is there a way i can stop it ?

Sorry if this is a stupid question but im trying to learn

Dont worry about it mate, you will just get a couple of drops out of the red pipes from the metering head...

The tank will stay full!

Excellent thought i was going to have to collect it in a bucket and use the fuel in the misses car !!!

So how does it stay in the tank ?

Do i undo it at the head or at the metering head end ? Which is best ?

Remove the fuel filler cap first to help release some pressure from the system.......

I think(!) fuel will only pass through the metering head when the air intake flap is pushed down. So when the flap is shut, no fuel can get through.

Probably best to take the red pipes off at the head, then you can tie them out of the way and they wont get damaged. There are two ways to do this;

1. undo the hex unions that the pipes pass through. (This is the union between the end of the pipe and the injector). Sometimes the whole pipe and injector will turn, and you dont want that to happen. If it does, proceed to step 2

2. undo the little (8mm head IIRC) bolt that holds the injector into the intake spacer. This way, the whole injector will pull out, still attached to the end of the red pipe. One or two of the little bolts are a bitch to get at though IIRC. Bag up the ends of the injector so they dont get shit on them.

Hope this helps!

Right have i been doing this all arse about face or what?
I undo all the 5 pipes off the metering unit and take the head off with the lines still atached takes 2 seconds and saves effing around with tiny bolts behind the inlet manifold, i took the head off my car in a service station on the m40 when it blew a cheap headgasket. Had the spares in the car as it was gonna be done soon so i changed it there and then took 45 minutes
