I recently purchased (and installed) a new gold rack dampener bolt - officially called a Adjustment Bolt at Rear of Injection Pump.

The bolt came with a Prechamber Screw Collar. Its the same gold color. Its round with threads on the outside. Its diameter is much larger than the bolt.

Are the two related for installation?

I didn't see any place obvious on the IP for it. It sounds like an engine part, but why would I get one?

Thanks

Biodiesel, Mobil Delvac 1, and Viton fuel lines!

The two are unrelated. The screw collar fits above the prechambers.

I'll be kind and refrain from commenting on the reason why you got one.................
