Key Features
- OEM-Grade Fuel Compatibility — Constructed from materials engineered to resist fuel degradation, maintaining a leak-free seal throughout the fuel delivery path.
- Correct Dimensions for Direct Installation — Cut and sized to the 3.51-50 specification, allowing it to connect to existing fittings and routing points without alteration.
- Broad Multiquip Fitment — Confirmed for MVH502DSB and MVH502DSB2 reversible plate compactors, MQ41TDH trash pump, and MDR-9D power trowel.
- Consistent Fuel Flow — A correctly fitted hose maintains steady fuel delivery to the engine, preventing lean-run conditions, hard starts, and unplanned stoppages.
- Fuel System Safety — A cracked or deteriorated fuel hose creates a fire and leak hazard; replacing with a genuine OEM hose restores proper containment and keeps the fuel circuit sealed.
A fuel hose carries fuel from the tank to the carburetor or fuel injection system, maintaining a continuous, pressurized flow that the engine depends on to run. Over time, fuel hoses can harden, crack, or develop pinholes due to heat cycling and fuel exposure, which can cause fuel leaks, air ingestion, and engine performance issues ranging from rough running to complete shutdown. Replacing a worn hose with the correct OEM-spec Multiquip 03961400 restores the integrity of the fuel circuit and returns the machine to safe, reliable operation.
