About this part
3098353 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 3098353, 3090942, ISM11, QSM11. Application recorded for this part: Fits Cummins.
Every injection event depends on this pump producing pressure at exactly the right moment. Because it also carries its own lubrication, poor supply pressure and fuel dilution do disproportionate damage — which is why the supply side should always be checked alongside the pump itself.
The pattern is normally cumulative: slightly harder starting, then noticeable power loss, then smoke and unstable idle. Where the drive seal has failed, diesel in the lubricating oil is the warning that should stop you running the engine.
Eliminate the cheap causes first: filter condition, lift pump output, suction-side air leaks, fuel quality. Only then have delivery quantity and timing tested before committing to a replacement unit.
Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate.
What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.
