Mk1 golf gti cab 1988

Anyone know the best place to buy new injectors for my 88 golf gti cab?

Vw Heritage have a few options.

Are they bad or Leaking, Some times removing them and cleaning them with B12-Cleaner by Berryman  can clean the gunk out and then the Spray returns to fine conical atomization.

CIS Injector Cleaning, Seal and Holder Replacement

There is 2 types of injectors, if you have a rubber pipe going to the head between cylinders 3 and 4 you need the air shroud injectors.
You should need this type (as that's what's in my 1988 car) if you have the original head, they seem to be getting expensive now, VW heritage are £66.10 each so £264.40 for 4! Gone are the days when they was £100 for 4.  
Might be worth giving them a clean first.

I believe you can swap to the earlier injectors if you find the cheaper….

Got them sorted thanks just needed new injector seals as I had a serious misfire but it's all solved now

you can fit either type of injector to either type of head, only issue is you have to swap the fuel lines to match them as the early non-shroud ones and the mercedes brass injectors are coarse thread, later injectors are fine thread.

if you end up with non-shrouded injectors for a head with shrouding system you have to either cap off the nipple on the rear of the head, or swap the top hats over from some shrouded injectors. if you go the other way just pull the top hats off and they go right in
