Before you order, you need to know what to do if the fuel KO drum gets liquids in it. Does it have a level controller or sight gauge? Does it have a switch? Some fuel KO have a ball float system where there is a ball in a cage attached to the outlet nozzel on the top of the KO. If liquids enter the ball floats up and shuts off the fuel. A lot of time the KO has a filter in it to remove even the smallest droplets or fine particles of rust, dirt and oils.
There are several shops that can help. Here is a nice one that will assist in the engineering too.
