Key Features

• Genuine OEM Sealing Integrity — Manufactured to Multiquip's original material and thread specification, ensuring a fuel-tight seal that prevents leaks and contamination on every fill.
• Direct Thread Match — Engineered to the exact thread pitch and cap diameter of the original, so installation is straightforward with no modification to the filler neck or tank.
• Broad GA and GAW Series Coverage — Confirmed fitment across GAW180HE, GAW180HEA, GAW135H, GA2.5HR, GA6HR, GA3.6HR, GAC6HR, GA6HEB, GA6HB, and related variants.
• Proper Tank Venting — Designed to maintain correct fuel tank pressure balance, protecting the fuel system from vacuum lock or pressure build-up that can disrupt generator or welder performance.
• Fuel System Safety — A correctly sealing fuel cap is a critical safety component on gasoline-powered equipment; this OEM replacement meets the original design standard to minimize spill and vapor risks during transport and operation.

The fuel cap seals the fuel tank filler neck, preventing fuel from spilling during transport or operation and keeping debris and moisture out of the tank. Most fuel caps also incorporate a venting function that allows controlled airflow into the tank as fuel is consumed, preventing a vacuum that would starve the engine of fuel. When a fuel cap is cracked, has a worn thread, or loses its vent function, it can cause fuel spillage, hard-starting, or erratic engine behavior — issues that are easy to avoid by replacing the cap with the correct OEM part.
