Multiquip 0605505070 Fuel Tank Cap

The Multiquip 0605505070 Fuel Tank Cap is a genuine OEM replacement designed for a wide range of Multiquip DCA Super-Silent, Ultra-Silent, and diesel-powered generator models, as well as DIS series air compressors. As a factory-sourced component, it delivers the exact fit and seal integrity the original design requires, covering models including DCA25, DCA45, DCA70, DCA125, DCA150, DCA220, DCA300, DIS100SSK4F, and DIS185SSI4F, among many others across the DCA and DIS families. Sourcing a genuine OEM cap means you get the correct thread pitch, venting spec, and material grade — no guesswork, no improvised substitutes. DHS Equipment supplies this part direct, so you can get your equipment back in service quickly.

Key Features

• Genuine OEM Seal Integrity — Factory-sourced cap maintains the correct pressure venting and fuel containment performance that the original fuel system was engineered around.
• Exact Thread and Dimensional Match — Designed to the original tank neck specification, seating flush and threading cleanly without modification to the filler neck or surrounding components.
• Broad DCA and DIS Series Coverage — Confirmed fitment across dozens of Multiquip Super-Silent, Ultra-Silent, and diesel generator models, plus DIS series air compressors — check your model code against the fitment list above.
• Fuel System Protection — A properly sealing tank cap prevents fuel contamination, controls vapor emissions, and guards against spills during transport or operation on uneven terrain.
• Fuel Safety Compliance — On diesel-powered equipment, a correctly venting and sealing fuel cap is a basic fuel system safety requirement; a cracked or missing cap creates a contamination and fire risk.

The fuel tank cap seals the filler opening on the diesel fuel tank, preventing debris, water, and contaminants from entering the fuel supply while also controlling vapor pressure within the tank. A functioning cap with the correct vent rating allows the fuel system to breathe properly — without it, fuel starvation, pressure buildup, or contamination can interrupt generator output or cause hard-starting conditions. When a cap cracks, loses its seal, or goes missing entirely, the risk of dirty fuel reaching the injectors increases significantly, making timely replacement a straightforward way to protect a much more expensive fuel system.
