Marine Fuel Injection Pump Supplier
Fuel injection pumps, plunger and barrel assemblies, delivery valves, high-pressure pipes and rack components for marine main and auxiliary engines.
The plunger and barrel is a lapped, matched pair with clearances measured in microns, which is why fuel injection pumps are unforgiving about fuel cleanliness and why they are almost never repaired by replacing a single component. When a pump loses delivery, the usual causes are plunger and barrel wear, a leaking delivery valve or a seized rack — and the fix is a matched element, not a part number picked in isolation.
We supply complete pumps, matched plunger and barrel sets, delivery valve assemblies, high-pressure pipes and the rack and control linkage that sets the fuel index. Reconditioned and test-bench-calibrated pumps are available where the OEM lead time will not work, supplied with the calibration report.
What We Supply
- Complete fuel injection pumps and pump housings
- Matched plunger and barrel (element) assemblies
- Delivery valves, holders and springs
- High-pressure fuel pipes, sleeve nuts and shock absorbers
- Fuel racks, control sleeves, toothed quadrants and linkages
- Pump roller guides, tappets, cam followers and rollers
- Suction and puncture valves, VIT (variable injection timing) components
- Reconditioned and bench-calibrated pumps supplied with calibration reports
Fuel Injection Pump Problems
- Low or uneven maximum pressure across units at the same fuel index
- Fuel index climbing over time for the same load and fuel quality
- Fuel leakage past the plunger showing at the pump drain
- Difficulty setting or holding the rack position; a sticking or seized rack
- Delivery valve seat leakage causing dribble and a smoky exhaust on that unit
- Knocking traced to a pump roller guide or cam follower
- Cat fine damage to the plunger and barrel after a fuel treatment failure
Engine & Equipment Makes We Cover
Fuel Injection Pumps supplied for the makes below, as genuine OEM and as class-approved equivalents — both quoted so you can decide against your survey date rather than guess.
What to Send Us for a Quote
Send the engine make and type, the pump or element part number and the unit number. If the pump has failed, tell us what you found — plunger scoring, a leaking delivery valve or a seized rack all point to different root causes and change what we recommend supplying alongside it.

Fuel Injection Pumps — Common Questions
What superintendents and purchasing teams ask us most about marine fuel injection pumps.
Do you supply matched plunger and barrel sets?
Yes. Plunger and barrel are a lapped, matched pair and must be supplied and fitted together — they are not interchangeable across sets. We quote them as one item for that reason.
Can you supply reconditioned fuel injection pumps?
Yes, bench-calibrated and supplied with the calibration report. This is a common route where the OEM lead time does not fit the docking window or the engine is out of standard production.
Do you supply high-pressure fuel pipes?
Yes, along with sleeve nuts, shock absorbers and the double-walled arrangements required for the fuel oil leakage alarm on modern installations.
What causes rapid fuel pump plunger wear?
Almost always abrasive contamination — catalytic fines that got past the purifier and the fine filter. Water in the fuel and prolonged operation on off-spec fuel accelerate it. If plungers are wearing fast, the fuel treatment plant is usually where the real problem is.
Do you supply VIT and puncture valve components?
Yes. Variable injection timing components, suction and puncture valves and the associated control linkage for engines fitted with them.
Which engine makes do you cover for fuel injection pumps?
MAN B&W, Wärtsilä, Sulzer, MAK, Yanmar, Daihatsu, Hanshin, Akasaka, HiMSEN, Caterpillar, Cummins and Deutz, across main engines and auxiliaries.
