    05 22v gas valve leaks

    Went to pick up my boat after winterization and the gas has leaked out and dripped so much that the cover was damp, gas on my trailer step and down the side of the hull and started eating the graphics. previous owner had this issue also and never could figure it out.

    I could heard air noise in the valve so there is something going on in there. Have any of you added a fuel/air separator to the vent tube? I saw some threads about malibus having this issue.

    It is still at the dealer so they can attempt to figure it out. I don't want to have to worry about this all winter.

    Id say take it out an burn off a couple of gallons of gas, but i guess its winterized. Fuel expands as it warms up. if the tank is full enough, it will purge out. Not filling the tank to the brim is the best solution and costs nothing and requires no mods.

      I am guessing you have the tank slam full. Had a little bit of a warmer day fuel expands and pushed out the vent. Had the same thing happen to me.I filled it slap full in the morning because we were going out after work and durung the heat of the day it pushed fuel out the vent. Satined my rubrail and ate my graphic. Not really anything to fix. just have to blow the vent and drain some gas and clean up the mess.

        I'm pretty sure that it was well below full, maybe 3/4 or so. I guess I'll know more Tuesday when they reopen.

          I have seen many posts about the same thing. In some of these posts, the decals have also been damaged due to the gas spilling out. They all have one thing in common, the gas tank was FULL.

          I fill my tank completely full and add the STAB to it. I then take the boat out for a nice ride for about an hour or two to burn off some of the gas and make sure the stab has gotten into the injectors.
          I then do my winterizing including Fogging.

            still a problem

            went to check on the boat after winterization and again this problem. it does not seem as bad as before they adjusted the vent tube. I backed off the gas cap a bit and there was a ton of air pressure. is that an indication of the problem? I can't keep worrying about this during storage as it is a combustion threat and keeps damaging the boat gel coat, rub rail, platform and graphics. any other insight is appreciated.

              Did the tech explain what the vent line adjustment was to address? Its the vent where the fuel or vapor pressure would be purging from. Can you determine whether the fuel is purging from the vent or the cap? Was an attempt made to lower the level in the tank? Thats still my gut feeling, especially since its not as bad this go'round.

                It was to address this issue. The previous owner had the same issues and never was able to resolve it. I intend to get to the bottom of it.

                They have verified that the check valve is in good working order. They re-routed the vent tube during winterization and this made it more straight. What is strange to me is that it routes down through my port side locker down in front of the motor then I'm not sure where it goes. It seems to go lower than the gas tank but I'm not certain and I have not traced it completely. Maybe I can go do that tomorrow. I assume the vent would be from the top of the tank as I've seen on diagrams online like the Perko website.

                Is my gas cap vent suppose to be vented? The fuel is definitely coming from the vent as the cap was on pretty tight against the rubber seal.

                  I know they were trying to fix this issue, but was their reason for "adjusting" the hose? was it too long, too short, kinked, wrong color, etc.

                  The vent port for the tank is on top, and I think over towards the port front corner. If the vent line is drooping below the level of the tank, I can see it collecting fuel when the tank is full. As the fuel level drops, the fuel will remain in the hose. As the fuel heats up and expands, the trapped fuel will be purged out by the vapor pressure behind it. Sounds like the hose needs to be laid across the top of the tank and secured. Maybe even shortened a little. I would pull the floor up and see.

                        The "what is this?" is the back side of the cleat. They have caps that catch water and allow for a drain tube to be attached. Thats the black plastic part.

                        Yep, thats the vent line, but you will have to pull the floor up to actually see the important section of it. It runs all the forward the length of the tank. If its fallen down along the side of the tank, I bet thats the root cause as described above.

                          The boat has been at the dealer all week to determine what is causing this issue. They rerouted the vent tube and replaced the check valve and also sent pictures to Tige. The tank currently is ~3/4 full.

                          Tige response - The aluminum tank filler and vent are at the transom end of the tank. If the tank is full and the boat is tilted up at the bow then naturally the air pocket is at the bow end of the tank and thus can cause the gas to exit. The solution is to store with the bow down. I guess their new tanks are setup differently.

                          Does this seem reasonable to have to perform this step?
