Multiquip 511383 Fuel Return Hose 1/4"-88"

The Multiquip 511383 Fuel Return Hose 1/4"-88" is a genuine OEM component designed for MQ600TD80-TLRB and MQ600TD80-TLRP trash pumps. Sourced directly from Multiquip, this hose meets the exact specifications of the original part and installs without modification to the factory fuel system routing. Correct fitment is confirmed for both the MQ600TD80-TLRB and MQ600TD80-TLRP models, giving you confidence before you order.

Key Features

• OEM-Grade Fuel Compatibility — Manufactured to handle the specific fuel pressure and chemical exposure of the MQ600TD80 series fuel return circuit, maintaining hose integrity over extended run cycles.
• Exact-Length Replacement — Cut to the OEM 88-inch specification, this hose routes and connects directly to the factory fuel return fittings with no trimming or adapters needed.
• Confirmed Model Fitment — Verified for MQ600TD80-TLRB and MQ600TD80-TLRP trash pumps, so you're ordering the right part the first time.
• Fuel System Integrity — A correctly functioning fuel return hose maintains stable fuel delivery pressure; a cracked or swollen hose can cause fuel leaks, rough running, or engine shutdown on the pump.
• Fuel System Safety — Replacing a degraded return hose with a genuine OEM part eliminates the risk of fuel leaks near hot engine surfaces, an important consideration on high-cycle pump equipment.

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 keeping delivery pressure consistent. Without a properly sealed return line, fuel can leak externally or introduce air into the system, causing hard starts, inconsistent engine speed, or unexpected shutdowns. On trash pump equipment operating in demanding jobsite conditions, a compromised return hose is a common cause of fuel-related service calls that an OEM replacement quickly resolves.
