When replacing the lift pump:
Feeds fuel from the tank through the filter/water separator to the injection pump, maintaining a steady supply.
Symptoms: hard starting, hesitation under load, air ingress, leaks at hose barbs.
GX-AFTER combines fitment and durability — consistent flow rate, robust housing and easy drop-in installation in the filter head.
Not always. Common causes also include a clogged fuel filter, a faulty relay/fuse, or wiring issues. With ignition ON you should hear a faint pump hum. If not, check supply voltage and ground first.
Electric vs mechanical lift pump — what’s the difference?Electric pumps provide a steady fuel feed regardless of engine RPM and make bleeding easier. Mechanical pumps (older machines) are engine-driven and their output depends on RPM.
Does this pump fit JCB DieselMax engines?No. 17/927800 is used with Perkins engines (RE/RG, 1104). JCB DieselMax-equipped machines require a different pump.
Key specs for this model?12 V DC supply, approx. 140 L/h flow rate, integrated filter head/water separator, cast + plastic housing.
Are 17/927800, 17/919300 and 334/D8880 interchangeable?Yes — these are the most common cross-references for the same application (Perkins 1104, TIER 2).
Can running on low fuel damage the pump?Yes. Prolonged operation on reserve promotes air ingestion and pump seizure. Avoid low-fuel operation and replace the fuel filter at recommended intervals.
