X15 116B Fuel Pump Head Replacement

[marek4792]

Doing a pump head replacement on mine at 780k miles because the check valve started leaking with no fault codes. Plunger was still good. However the rollers can't be sourced, but looks and feels good. Guess Allison over in Haggai was right about these pumps being more robust.. Kinda pricey bastards though, if you want to do both literally cheaper in the long run to get a new pump...
Anyways, here's the part numbers for everything if anyone needs it..
-Fuel pump head kit #6310580PX
-Oring not included #3028349
