Fuel Feed Pump Priming Pump 1-15761006-0 1157610060 for ISUZU FVR34 6HK1
Fuel Feed Pump Priming Pump 1-15761006-0 1157610060 for ISUZU FVR34 FSR NPR 6HK1 4BG1 6BG1 — OEM Quality
Product Overview
The Fuel Feed Pump Priming Pump with OEM numbers 1-15761006-0 / 1157610060 (alternate 1-15761006-1 / 1157610061 / 1-15610-006-0 / 1156100060) is a verified direct-fit replacement for ISUZU 6HK1, 4BG1, 6BG1, 6WG1 series diesel engines. This hand priming pump is a critical auxiliary component of the diesel fuel system, responsible for manually pumping fuel before engine start-up or after fuel system service to purge air from the system and ensure smooth engine starting.
How It Works
The fuel feed pump (hand primer pump) is installed near the fuel filter or injection pump, consisting of a manual pumping mechanism (button or handle), diaphragm/plunger, and inlet/outlet valves. When the engine is stopped or air enters the fuel system, the operator manually presses the pumping button, causing the diaphragm/plunger to reciprocate, drawing fuel from the fuel tank through the fuel filter into the pump chamber, then forcing it through the outlet valve into the injection pump. Through repeated operation, air is purged from the fuel system through the air bleed screw until no bubbles are present in the discharged fuel and system pressure returns to normal. This pump ensures that the engine can quickly build fuel pressure during cold starts, after fuel filter replacement, or after fuel system service, solving hard starting and flameout problems caused by air blockage.
Failure Symptoms
Replace immediately if any of these symptoms occur:
- No Resistance When Pumping — Pumping button feels soft and cannot build fuel pressure (damaged diaphragm or failed seal)
- Fuel Leakage — Visible diesel seepage from pump body or connections (aged seals or cracked housing)
- Continuous Air Entry into Fuel System — Engine still hard to start or runs rough after bleeding (internal seal failure allowing air ingress)
- Pumping Button Sticking — Button fails to return automatically or is difficult to press (failed internal spring or stuck plunger)
- Engine Stalls After Starting — Fuel system cannot maintain pressure (failed check valve in hand pump)
- Hard Cold Starting — Extended pumping required for every cold start (degraded pump efficiency)

Important Installation Notes:
- The hand primer pump is a critical maintenance component of the diesel fuel system — seal failure causes air ingress into the fuel system, leading to hard starting and power loss
- Recommended to replace fuel filter and copper washers simultaneously when replacing the hand pump for proper sealing
- Manually pump fuel to bleed air from the fuel system after installation until no bubbles are present in the discharged fuel
- Use a torque wrench to tighten connections to specification — avoid over-tightening which may damage threads
- For 100% accurate fitment, please provide VIN or engine model

Installation & Maintenance Recommendations
IMPORTANT: The hand primer pump is a critical component of the diesel fuel system. Improper installation may cause fuel leakage and air ingress into the fuel system, leading to hard starting and power loss. Installation should be performed by qualified professionals. Ensure the engine is completely cooled and fuel system pressure is released before installation.
Installation Guidelines (Refer to workshop manual):
- Safety Prep: Disconnect battery negative terminal; ensure engine is completely cooled; release fuel system pressure
- Clean Exterior: Thoroughly clean oil and debris around the hand pump to prevent contaminants from entering the fuel system
- Remove Old Hand Pump: Disconnect fuel lines and mounting bolts; remove old hand pump (catch draining fuel)
- Clean Mounting Surface: Thoroughly clean mounting surface and threaded connections; remove old seals and debris
- Install New Hand Pump: Mount new hand pump in original position; install new copper washers
- Tighten Connections: Torque connection bolts and fuel line fittings to workshop manual specification (must use torque wrench)
- Manual Bleeding: Repeatedly press hand pump button while opening fuel system air bleed screw until no bubbles are present in discharged fuel
- Check for Leaks: Check hand pump and fuel line connections for fuel leaks
- Start Engine: Start engine; confirm normal starting, smooth operation, and no abnormal noise
- Road Test: Perform road test — confirm normal power, no stalling, no leakage
Maintenance Schedule:
| Item | Interval |
|---|---|
| Fuel Filter Replacement | Every 10,000-20,000 km |
| Hand Pump Seal Inspection | During each service |
| Hand Pump Replacement | Must replace when weak pumping, fuel leakage, or hard starting is found |
