What's this?

Noticed this today while messing with the pump. Not to sure what it is and if that clip on the back is important because the wire going into it hast been connected for who knows how long. Just wondering if this is important and what it does. Thanks

That's the KSB, or cold start advance, for your pump. What year truck is it on?

If it's a 98-91, or non-IC'd, it needs to be hooked up for the pump to function correctly under normal circumstances, if it's late91-93, or IC'd, it doesn't need to be hooked up for the pump to function correctly, but it needs to be hooked up for the KSB to function.


:edit:

n/m, I see the later vacuum pup down there. It will run and function fine unhooked, you'd just need to have it hooked up for the cold start timing advance to function correctly.
