The Multiquip M3311500703 Surge Tank Hose is a genuine OEM component designed for the DCA150SSJU4F diesel-powered generator. As a direct OEM replacement, this hose is manufactured to the exact material grade, diameter, and routing specifications called out for this machine — no guesswork on fitment. Sourced directly from Multiquip, the M3311500703 ensures the cooling system surge tank circuit operates exactly as engineered for the DCA150SSJU4F.
Key Features
- OEM Material Integrity — Constructed to the exact compound and wall-thickness spec required for sustained coolant contact and heat cycling in diesel generator cooling circuits.
- Direct Routing Match — Matches the original hose path and end-fitting dimensions on the DCA150SSJU4F, allowing straightforward installation against existing clamp positions.
- Confirmed Fitment — Verified for the DCA150SSJU4F ultra-silent diesel generator series.
- Coolant System Integrity — A sound surge tank hose maintains proper coolant pressure and flow to the expansion tank; a cracked or collapsed hose can cause air ingestion, coolant loss, and generator overheating under load.
- Genuine OEM Assurance — Supplied as a genuine Multiquip part, carrying the same part number — M3311500703 — used by Multiquip dealers and service technicians worldwide.
The surge tank hose connects the engine cooling system to the coolant expansion or surge tank, allowing hot coolant to expand safely and return as the system cools down. This controlled flow prevents pressure buildup and keeps the cooling circuit at a stable operating level during extended generator run times. When this hose deteriorates — through cracking, swelling, or pinhole leaks — coolant level drops, coolant system pressure becomes unstable, and the risk of engine overheating increases significantly.
