Injection pump o-ring part number needed (1 Viewer)

[Tanner H]

got a leak coming from one location on the bottom of my kzj78 injection pump. The rest of the pump looks dry and good. I tried slightly tightening the Allen bolts but no luck. Anyone know what part number this is? Or if anyone has it leftover from a reseal kit they don’t need.

Circled the area leaking. I believe this is the timing valve. Found the part and it comes with the o-ring, but can’t find the damn o-ring number on its own

Not available as a service part. Buy the switch, get the o-ring.

Otherwise, match it up with an o-ring rated for diesel fuel.

@OGBeno thanks man. I was hoping you’d see this and chime in.

Got the part out and found the ring to be in great condition! Haha.

Swapped out the ring with a metric nitrate. Seems to be holding up great. Time will tell.
