>>>> CAP?? ON INJECTOR PUMP R2500 ???

[BearKiller]

On the top-rear of the injector-pump of my R2500 is a metal "jiggle-cap" with a copper?? or bronze?? mesh filter inside the caps perimeter.

This cap is very much like the jiggle vent-caps found on truck transmissions, rear-ends, etc.

What purpose does this cap serve ??

Thanks.
