Question for the TD42 injection pump gurus

[jff45]

Here's a pic of the pump on the engine I just bought.
Can anyone tell me what the electrical thingy (technical term) is under the green dust cover.

I showed the pic to Mat this morning and he'd never seen it before..

Well you learn something new everyday. I see you have got the answer on the other forum.

Yep, as you saw, it's a cold start advance mechanism. Creates the advance by restricting the return flow.
Did I get that right?

Yep.

It will be fine to remove it. Just grab the appropriate banjo bolt from an injection shop. I have never seen one on an au delivered td42.

Any reason I can't just leave it there and not connect it?

[nissannewby]

Should be fine.
