I'm taking the Blue Funk apart and have removed all the sheet metal. I'm down to the cab. I've drained the gas tank and am wondering about the stopcock. Does that stopcock screw off of the tube that descesnds fom the tank?
I've read past posts on gas tank removal but don't seem to remember any specifics about stopcock removal.
Your input is appreciated.

The brass tube unscrewed from the tank complete with the valve.
I then managed to separate the tube from the main valve body.
It was pretty gummed up but did come apart eventually after soaking it in fresh gas for a couple of hours.
Mine is from a '50 but I'm assuming yours will be the same.

The stopcock on the Blue Funk looks a little different from yours, Tiny. It has a relatively long tube descending from the tank. On the bottom of the stopcock is a 6-sided 1/2 inch bolt head. The control is on the left and the line goes off to the right to the carb.
I'll play around with it and let you know what I find.

The nut is actually a plug and drains the tank if you take it out | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | here is another type ...pic... ...pic... as others have posted, pipe thread Good Luck | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 |

I stuck a socket on it and the gas cock turned right off. The gas tank was the last thing I had to remove before removing the cab. Save for removing the right running board, which a PO had welded onto one of the supports, all the sheet metal has been removed from the Blue Funk's frame. Thanks for all the pics and info. | | |
