I’d like to change the fuel pump on a disco 1 auto back to a manual pump and remove air mass metre, what is the best way/modification to still have the kick down facility ?.
TIA

You should be able to fit the kick down bracket on to the manual pump..

You need a bracket from a manual pump fitted to an auto.

Indeed :). 'bout a £100 notes from LR :eek:, so try and find one in a breakers yard is my advice. Tis a simple job - but keep all your emissions control sh*t for the next MOT ...... ;)
 
If you fit the mechanical FIP, make sure you get all the emissions crap that goes with it, and then it should be OK the year after too - it only has to be there - they can't, as yet, test that it is working :rolleyes:.

As I'm sure u know, to return to the manual fuelling system will have a detrimental effect on the performance of your vehicle, so what's wrong with fitting a replacement air mass meter ? that seems simple to me, but then I've never see a Diesel engine and don't won't too. :)

As for emissions, my understanding is that the test for a both of the D1 fuelling systems is the same simple test i.e. the amount of smoke emitted from the exhaust tail pipe.

You will also need to change the injectors. I have just had mine done as I wanted to be able to play around with the pump. Had the pump set to standard before it was put in then I have dropped a boost pin which has made a great difference. Going to put one of those timing bits in next before I start to make any further changes!

I think the performance will be a lot better with the egr and air mass metre delete with a mechanical pump retro fitted on.

True - when I de EDC'd mine I changed them for reconditioned standard ones :)

It won't. 300Tdi EDC were 122 HP - 300Tdi VE pump was 111HP. The air flow meter is an essential part of the EDC - thus the 122HP is with it in place.

A properly tuned FIP with a FWIC will be better, a lot better , but EGT increases rapidly and will anneal the head unless you are very careful - which is why LR fitted EDC.
 
I fitted a home made chip from one of the forums but it really didn’t make any difference on mine. I could never get to the bottom of why my EDC never felt right. Gutless unless driving down a cliff. At least now I can tow better and maintain some reasonable progress in the old girl!
