Tank distribution valve

[michael bustamante]

So this 67 I just picked up has three gas tanks. Two saddles and one in the cab and I'm pulling them all out and cleaning them and replacing all the lines of the lines are full of varnish gel and the tanks or have old gas in them needs to be cleaned out and flushed. But my question is about the distribution valve which is located right under the driver side seat. How in the heck do you take this off the cab of the truck? Am I going to have to remove this carpet to get to it or can I just take the school off of the handle and unscrew it from the bottom?
