Portable fuel tanks

[bulletsaltcreek]

Can anyone tell me the term (name) for the piece that screws in to the top of the gas tank? Withdraw assembly? What I'm looking to do is replace the guage/fitting on the top of my 12 gallon tank. I've looked everywhere for this all I've was the gaskets and screws. It has 6 screws and a fitting that the fuel line goes into from the motor.
It may sound shallow but I can't find this particular part. Maybe because I haven't searched the right term. Any links will be appreciated as well
Thanks!!

Need more info. What brand do you have? "Pick up assembly" is where I would start, but each brand has their own style.
