Key Features
- OEM-Grade Fuel Hose Construction — Built to withstand fuel exposure and operating pressures specific to the fuel return circuits found on Multiquip concrete pumps and ride-on rollers, maintaining hose integrity over extended service life.
- Direct OEM Replacement — the part installs into the fuel return line routing exactly as the original, with matching 5/16 in. inner diameter to connect properly at both the engine and fuel tank fittings.
- Broad Cross-Equipment Fitment — Confirmed for C30HDG, C30HDGA, LS-series concrete pumps (LS300, LS300GK, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, LS60TD, LS450), and AR-series rollers (AR13H, AR13D, AR13HAR).
- Protects Engine Fuel System Integrity — A sound fuel return hose keeps excess fuel cycling correctly back to the tank, preventing fuel starvation, rough running, and potential fuel leaks at the return circuit.
- Fuel System Safety — A cracked or deteriorated fuel return hose can allow raw fuel to contact hot engine surfaces; replacing it with a correct OEM hose removes that fire and safety risk.
The fuel return hose carries excess fuel from the engine's injection or carburetor system back to the fuel tank, completing the fuel circuit and helping regulate pressure within the system. Without a properly functioning return hose, engines can run poorly due to irregular fuel pressure, or develop fuel leaks at degraded connection points. On demanding equipment such as concrete pumps and ride-on rollers, where engines run under sustained load, a compromised fuel return hose should be replaced promptly with a correctly sized OEM part like the Multiquip 514536 to restore proper fuel circulation and safe operation.
