I want to remove the tank to do some maintenance and check the suspect hose clamps etc over the winter. I have read the shop manual and it says "drain tank and remove unions from flange". No further instructions. After seeing the scary pictures in the FIREBALL thread and looking at the somewhat cheezy and delicate looking plastic "unions" I thought I should ask the proper procedure for "removing unions from flange" before I break them by prying/twisting/squeezing them improperly. Also I am curious if the fuel actually needs to be drained or if it will stay inside the tank rather like an air quick disconnect keeps the air inside. After I was shut out, my 12 year old son pleaded with SWMBO (without my prompting I might add) to help up his cool factor with his buddies when they come over to play by letting me keep the Duc in the family room over the winter. She can't refuse him anything, so I don't want any gas smell escaping and causing rescindance of the privelidge of warm inside storage. Or loss of the fine view from the couch. If the gas stays inside, I can drain it out in the garage after removal to preserve the peace. Thanks for sharing your insight and experience!
