300tdi injector pump question

My 96 Disco injector pump has a lever the function of which I do not understand. Perhaps someone here can fill me in.

On the side of the pump closest to the engine block, there is like a vertical lever close to the top of the pump body.
This lever has an adjustable push rod attached to it with a long spring which runs up to the throttle lever.
When the throttle is operated, the lever moves a little.

What is the function of this lever and how is it adjusted ??

Mine is disconnected and some parts have been lost but the car seems to run fine.

I have seen pictures of pumps from other years and they dont seem to have this lever.

Thanks, Steve

Dont fix it if it's not broken

lever it alone

Pictures please...

I think its part of the throttle position sensor for the egr system. if your egr has been removed it will be a non functioning part

This is not my pump but one on ebay that is just like it.
The lever I question is clearly shown. It looks like an inverted "T" close to the top of the pump, behind the black fuel line. The long spring is quite visible too.

I do not believe it has any connection to the EGR system (mine is disconnected anyway) as it works somehow on the inside of the IP.

Thanks for any help.

from past experience the moto if it works leave well alone has served me well.

Well I have left it alone for some time. As an engineer, somehow I need to know what its for. Perhaps I could be getting 0.1 more mpg or even 0.2 HP more or something really important

its a bit weird I dont have that on my pump but I do have something else thats not on the pump you pictured

is it anything to do with cold start?

I suppose thats possible. Normally the cold start is accomplished by a slight advancement of the timing and its done right at the bottom of the pump. On older VW's for instance there was a cable to pull, a bit like a manual choke, that you push in when the engine is warm.

I don't see anything that can convey the engine temperature in this case.

Your pump may be different if its later than the 96 model that mine is, and not have that lever.

The ebay seller has another 300tdi pump listed and it clearly shows the shaft and spring also shows the EDC unit.

Usually pumps with EDC dont have a lever to connect a cable. All is done electronically.
