removing injectors NF / NG engine
 

Hi,

I finally got some replacement fuel lines for my car (the pipes from the metering head to the injectors have rusted away and split).

It is a 1990 Audi 100 quattro with the NF 2.3 engine.

I have removed the 6 fuel lines (5 injectors and 1 cold start valve) from the metering head.

The Haynes manual says "unscrew fuel lines from injectors, replacement is the reverse of removal".

I tried to unscrew the pipes from the injectors, but the injectors came out of the inlet manifold, complete with a plastic insert they sit in.

In this diagram:

the insert is part number 9, part 6 is the injector (usual metal tube thing)
(insert for injector part number 026133557A)

The injector spins round and round in the insert, but won't come out. I have the injectors sat in a bucket of petrol to try and clean out any crap.

HELP ME!!!! How do I get the injectors out? Brute force?

Thanks

Steve

if theyre the same as a WR quattro, just need a screw driver to ease them out, held in place by a rubber seal with the injector enclosed in a yellow plastic sheath.

I will have a quick try tomorrow.

If they were anything like the injectors in my DZ engine, brute force was the only way. lost some skin off my hand too :o
Mole grips and a hammer did the trick. :)

I got them out with a screwdriver. Just got to get new seals (aarrfff aaarrrff) tomorrow afternoon.

Then try and remove the injectors from the pipes...... Plusgas here we come!

Then put the thign back together.

get new sheaths as well, only a couple of quid and new seals, injectors should slide out.;)
