Thanks a million Peter ! I'm putting together a 300Tdi from a Japan-version Disco which came without the EDC and trying to mate it with a non-EDC injector pump that came out from a Defender. Do I have to change the injectors ?

Take a look at the No 4 injector, if it has an electrical connection to it or it looks bigger than 1 to 3, then yes you will need the injectors for the non EDC unit.

Hi Peter,

I had a thorough look at the injectors and they all looked physically the same(no electrical conn.on #4).The engine came intact from a Japanese Disco wreck(extremely low milage), complete with the electroniccally controlled injection pump but unfortunately without the EDC and all the wiring being snip-cut. The Defender manual injection pump has different nipples(short threaded pipe between pump and pipes to the injectors)to the ones on the original EDC pump, so I exchanged them thinking they might have different pressure and/or fuel quantity rating. My problem is really that it doesn't produce power. It starts easy, idles smoothly, revs easily under NO load. But as soon as I put it in gear/drive, it's lagging and doesn't accelerate and would take ages to come up to speed. Any idea ?

You got me stumped, if the Japanese engine was EDC I'd have expected to see No 4 injector with wires connected!!! The symptoms you describe sound like fuel starvation to me.

Season Greetings ! I stand corrected Peter, the #4 injector is indeed wired and a bit longer than the other 3. I should have looked into them myself first before writing. Would you think if I changed them with the correct Defender injectors, it would resolve the problem ? Do the nipples(short on the Disco/longer on the Defender)have a big effect on fuel supply also ? Do you happen to know a economical source for the injectors and injection pump(used) ? Appreciate your time !
