Bleed off pipes are the braided rubber pipes. yep go between the injectors and one links back to the pump.

Not sure on the 200 and std injectors but don't see why not, just have to measure and make sure they are the same size and won't hit anything.

The washers are copper ones that crush up and fit on the injectors to seal them I get them from a land rover parts place or that DMGRS place has them. https://www.dmgrs.co.uk

think you can get them ultra sound cleaned, don't know the price. I keep away from cleaning them so I don't block anything up!!

:):):)

you can fit the later injectors to the older engine, but it will be slow - the SDI's flow more fuel hence why you get a about 30bhp improvement just fitting them without a remap!

copper washers from rimmer bros or a landrover dealer (MGRdiscount site might have them too but not looked).

In theory you can get the separate new injectors nozzles for the SDI's, but honestly it's probably not worth it - just swap the nozzles over in a clean environment if you want the higher brake pressure injector (slightly less fuel, slightly cleaner) or just bung em in as they are :)

So are you saying to fit the SDI injectors BUT use the original nozzles from the ZS?

This is all new to me. Do the nozzles just unscrew from the injector?

Will doing this still give me the same extra fuel & bhp just with a cleaner exhaust ?

just fit the SDi injectors straight swap 30 + bhp gain.

I get a puff of black smoke when flat to the floor, but soon clears.

As we say, No poke, without the smoke.
