Moeller Withdrawal Assembly for Ultra Portable Fuel Tank — 621002-10, Fits 3 & 6 gal, Factory-Equivalent Replacement

The Moeller 621002-10 Withdrawal Assembly is the factory-equivalent replacement part designed to restore fuel withdrawal performance in Ultra 3- and 6-gallon portable Moeller tanks.

When a fuel tank’s withdrawal assembly wears, leaks, or becomes unreliable, replacing it with a matching factory-spec component preserves the tank’s original fit and function. The 621002-10 is built from the same components used in the original Moeller Ultra tank construction, so it installs cleanly into both the 3-gallon (62003 and 620003LP) and 6-gallon (620049 and 620049LP) models. Whether you maintain commercial equipment, recreational gear, or a backup fuel supply, this assembly is the straightforward fix to regain dependable fuel access without replacing the entire tank.

This withdrawal assembly replaces the worn or damaged components that control fuel flow and sealing in the tank’s withdrawal port. Installing the 621002-10 returns the tank’s original withdrawal performance by using parts matched to the factory specifications.
