Moeller 621002-10 Fuel Tank Withdrawal Assembly
Moeller 621002-10 Fuel Tank Withdrawal Assembly — Product description
The Moeller 621002-10 is the replacement withdrawal assembly for Ultra portable fuel tanks, the threaded fitting that seats into the tank and gives your fuel line a clean, sealed connection. It's a direct swap for the 3 gallon and 6 gallon Ultra tanks.
If you've got a Moeller Ultra portable fuel tank and the fuel line connection has started leaking, cracked, or just won't seal anymore, this is the part that fixes it. The Moeller 621002-10 is the withdrawal assembly, the fitting that threads into the top of the tank and gives your fuel line a clean, sealed connection. It's a direct replacement for the assembly that came on your tank from the factory.
This one fits two of Moeller's most common portable tanks. The 3 gallon Ultra (part numbers 620003 and 62003LP) and the 6 gallon Ultra (620049 and 620049LP). If you're running one of those on a small outboard, a kicker, or a portable setup, this is the assembly that lives on top of the tank.
The connection is threaded female on one side and threaded male on the other, molded in black to match the tank. The female thread seats into the tank fitting. The male side is where your fuel line connector attaches. It's a simple swap, but it's the kind of part that matters. A withdrawal assembly that doesn't seal right will pull air, and an outboard that's sipping air instead of fuel runs rough or stalls at the worst possible time.
Why replace it instead of the whole tank? Because the tank's usually fine. It's the fitting on top that takes the abuse, getting stepped on, baked in the sun, and cracked over a few seasons. Swapping just the withdrawal assembly gets you back on the water for a fraction of the cost of a new tank. If your fuel line is old too, replace that at the same time and you've essentially got a fresh fuel delivery setup.
Installation is straightforward. Thread the assembly into the tank and snug it down, then connect your fuel line to the male fitting. Don't over-tighten, and check the seal before you head out. This is the withdrawal assembly only. It doesn't include the fuel line or hose, so if yours needs replacing, grab that separately. When in doubt about which Ultra tank you have, check the molded part number on the tank itself against the list above.

Frequently asked questions
Which fuel tanks does the Moeller 621002-10 fit?
It fits the Moeller Ultra 3 gallon tank (620003 and 62003LP) and the 6 gallon Ultra tank (620049 and 620049LP). Check the molded part number on your tank to confirm before ordering.
What exactly is a withdrawal assembly?
It's the fitting that threads into the top of the tank and gives your fuel line its connection point. Fuel is drawn up through it and out to the engine.
Does this come with a fuel line or hose?
No. This is the withdrawal assembly only. If your fuel line is worn, pick one up separately.
What are the connections on it?
Threaded female on the side that seats into the tank, and threaded male on the side your fuel line connector attaches to.
Is this a genuine Moeller part?
Yes, it's the genuine Moeller 621002-10 assembly, the same part that ships on the Ultra tanks from the factory.
Why replace the assembly instead of the whole tank?
The tank itself usually outlasts the fitting on top. Swapping just the withdrawal assembly saves you the cost of a new tank when only the connection has failed.
