Multiquip 0191300400 Return Hose

The Multiquip 0191300400 is a genuine OEM Return Hose designed for DCA series ultra-silent and super-silent diesel generators, including the DCA70USI2, DCA45SSIU4, DCA400SSI4F, DCA600SSV4F3B, and related CAN and international variants. As a direct Multiquip OEM part, the part is manufactured to the same specifications as the original component installed at the factory, ensuring a correct fit across the full range of compatible DCA generator models. Sourced directly through an authorized Multiquip distributor, this Return Hose is the dependable choice when servicing your generator's fluid return circuit.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specifications, with hose material and dimensional tolerances matched to the DCA generator platform's fuel or coolant return circuit demands.
• Drop-In Replacement — Engineered to connect directly to the existing fittings and routing path on compatible DCA models, with no reworking of adjacent lines or brackets needed.
• Broad DCA Series Compatibility — Confirmed fitment across DCA70USI2, DCA45SSIU4, DCA45USI2, DCA45USI4CAN, DCA70USI3CAN, DCA400SSI4F series, DCA600SSV4F3B, DCA600SSV4F3PB, and related variants.
• Maintains Fluid Circuit Integrity — A correctly functioning return hose keeps fluid pressure balanced within the system; a cracked or degraded hose can lead to leaks, pressure loss, and unplanned generator shutdowns.
• Fuel System Safety — On diesel generator applications, a compromised return hose poses a fire and fluid contamination risk; using the correct OEM replacement maintains the integrity of the sealed fuel return path.

The return hose carries excess fuel or coolant fluid back to its reservoir or tank after it has passed through the engine or injection system, completing the closed-loop circuit that keeps the generator running at a stable operating temperature and pressure. On high-output diesel generators like the DCA series, this hose is under continuous thermal and mechanical stress, and degradation over time can cause seeping joints, soft spots, or full line failure. Replacing a worn return hose with a genuine Multiquip OEM part like the part restores the circuit to its original flow and pressure specifications, protecting the engine from fuel starvation or coolant imbalance.
