F150 fuel/vapor canister

[PAkev]

Today I made a little trip to the New York boat show and talked with the Yamaha folks for a while about their recommended winterization procedures.<br /><br />Although I fogged the cylinders and some other normal end of season winterization procedures, they also recommend draining the fuel/vapor canister of any residual fuel. They indicated residual varnish collected in this can diminish fuel supply to the fuel pump which can then burn out the fuel pump. On the way back home I started thinking this over and have become worried of not turning this stone over in my winterization procedure. In addition to no mention of this in the owners manual's storage procedure, the dealer (yamaha authorized) did not mention anything about this when discussing winterizing. Therefore, I am wondering if it is indeed something they do on a routine service level or if it is one of the first places they check when a problem pops up. <br /><br /><br />What gives me a little better peace of mind is that prior to my last time out I dumped a can of SeaFoam into the tank and upon winterizing and fogging I also added Stabil fuel stabilizer. Therefore, I believe I conditioned the fuel fairly well to diminish severe varnishing. I'm wondering if this is sufficient for the boat to sit another 3 months throughout the winter or if I should take the cover off the boat and attempt to pull the fuel/vapor canister off to clean out any remaining fuel?<br /><br />Helpful advice appreciated.

Re: F150 fuel/vapor canister

You should be okay, but my philosophy is "If it ain't in there, it can't go bad". There is a drain screw at the bottom of the Vapor Seperator Tank (what you're referring to). There is also a vent valve behind a small black rubber plug towards the top of the tank about 3 inches above the drain. You'll need a screwdriver to loosen the drain a turn or two and a needlenose pliers to remove the vent plug. Behind that plug is a valve just like on your tires. Push that in and hold until all the gas drains out. It holds about a cup to a pint of gas, so have a container handy to catch it. Except for the hood, you don't have to remove anything from the motor to do this.

Thanks WillyB<br /><br />While we are having 40+ degree temps here in the North East, I think I may attempt to uncover the motor and drain the tank. <br /><br />Although I plan to have the dealer provide routine seasonal service throughout the warranty parameters, it is over a 100 mile round trip to leave it and another 100 mile round trip to get it so I try to do what I can on the preventitive maintenance side of things.<br /><br />Kevin

According to the authorized repair center I was told that if you can start your engine once a month and bring it to operating temp thru the winter the only winterization necessary is to add fuel stabilizer to the tank to keep it fresh. I have the ability to do this and have had no problems with my F150!

Thanks cthru,<br /><br />I feel pretty confident that things will turn out A OK with the extra dose of conditioner. We are bordering sub 0 temperatures here in the northeast so starting the motor up on muffs once a month is certainly out of the question. About 2 more months to go until I'll pull the cover off and fire her up.

hello<br /> if you drain be aware it tkes 30 min or so to drain. if not the fuel in the actual pump will puddle in the bottom and varnish up. I usually add conditioner and leave it be.
