Multiquip 0605505072 Fuel Tank Cap

The Multiquip 0605505072 Fuel Tank Cap is a genuine OEM component designed for DCA Ultra-Silent and Super-Silent generator series, including the DCA25USI, DCA45USI, DCA70USI, DCA125USI, DCA150USJ, DCA150SSJU, DCA180SSJU, DCA220SSJU, and DCA300SSJU families. Sourced directly from Multiquip, this cap is manufactured to the exact specification of the original part it replaces. Whether you are servicing a Tier 4 unit or an older DCA-series generator, part 0605505072 ensures a correct, secure seal on the fuel tank. Keeping the fuel system properly sealed is essential to safe, uninterrupted generator operation on any worksite.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the original material and thread specification, ensuring a fuel-tight seal that aftermarket caps may not consistently deliver on DCA-series generators.
• Direct Drop-In Replacement — Threads directly onto the OEM fuel tank neck with no modifications to the cap, tank, or filler neck assembly.
• Broad DCA Series Coverage — Compatible with a wide range of DCA Ultra-Silent and Super-Silent models, including DCA25USI, DCA45USI, DCA70USI, DCA150SSJU, DCA180SSJU, DCA220SSJU, and DCA300SSJU variants.
• Fuel Containment and Vapor Control — A correctly sealed tank cap prevents fuel seepage and vapor escape during transport and operation, protecting both the equipment and surrounding personnel.
• Fuel System Safety — An improperly sealed or missing fuel cap on a generator creates a fire and contamination risk; replacing a worn or damaged cap promptly is a straightforward safeguard with significant consequence.

The fuel tank cap seals the opening of the generator's fuel tank, preventing diesel from spilling during operation, refueling, or transport. It also keeps debris, moisture, and contaminants out of the fuel supply, which is critical for protecting fuel injectors and the engine itself on high-output DCA-series generators. When a fuel cap is cracked, has a worn thread, or no longer seats properly, it can allow fuel to leak or introduce contaminants that degrade engine performance and create unsafe conditions.
