Multiquip EE1237 Fuel Fill Box with 4" Fitting Assembly

The Multiquip EE1237 Fuel Fill Box with 4" Fitting Assembly is a genuine OEM component designed for CG500C2 and CG500V4F series containerized generators. As a direct Multiquip OEM part, it is manufactured to the exact specifications of the original component, ensuring a correct, trouble-free installation on your generator system. This assembly is the right choice when restoring fuel access and fill functionality to CG500-series units operating in demanding commercial and industrial environments.

Key Features

• Genuine OEM Construction: — Built to the exact dimensional and material tolerances of the original assembly, ensuring the fuel fill port seals and connects correctly within the generator enclosure.
• Integrated 4" Fitting: — The included 4" fitting is pre-assembled into the box housing, allowing direct connection to the generator's fuel fill line without additional adapters or fittings.
• Confirmed Fitment: — Verified compatible with Multiquip CG500C2 containerized generators and CG500V4F diesel-powered generators — verify your model before ordering.
• Fuel System Integrity: — A properly functioning fuel fill assembly prevents fuel spillage, vapor escape, and contamination during refueling, protecting both the generator and the surrounding enclosure.
• Safety-Critical Component: — The fuel fill box provides a sealed, controlled refueling point on enclosed generator sets; using a correctly rated OEM assembly supports safe fuel handling in line with generator system design.

The fuel fill box assembly provides the access point through which diesel fuel is introduced into a containerized generator's fuel tank during refueling. It integrates a fitting that connects the external fill point to the internal fuel line, keeping the process sealed and controlled within the generator enclosure. When this assembly is cracked, corroded, or improperly fitted, it can result in fuel leaks, refueling spillage, and potential vapor accumulation inside the container — all of which present serious safety and operational risks.
