Possible Causes
Partially clogged fuel filter, Restricted fuel tank vent, Weak fuel pump, Faulty fuel pressure regulator (gas units)
How to Fix / Troubleshooting
Safety first: Turn OFF the generator and open the main breaker. Allow moving parts to stop before inspection.
- Step 1 – Loosen fuel cap (diesel): Slightly loosen the fuel tank cap and attempt to run the generator. If it runs longer, the tank vent may be blocked. Clean or replace the vented cap or vent line.
- Step 2 – Replace fuel filter: Install a new Multiquip‑specified fuel filter and prime the system. This is a common cause of short‑run stalling.
- Step 3 – Check fuel pump output: With a pressure gauge (for gas) or flow test (for diesel), verify that the fuel pump delivers adequate pressure/flow. Replace the pump if below spec.
- Step 4 – Inspect fuel lines: Look for collapsed, kinked, or soft hoses between tank and engine. Replace any suspect sections.
