        after filling my mako for the first time after purchase I found gas in the bildge. I lifted the center console(m20) and inspection hatch and found the fill pipe was rotted between the tank and the outside fill on the gunnel. worse yet the vent pipe was also rotted. Why this was ever made out of thin wall aluminum I'll never know. I ended up rerouting the fill with uscg approved fill hose to the side of the center console. this makes a nice 3 ft. drop to the tank. I installed a new fill bracket and grounded the whole setup.

        next I ran a new 5/8 vent hose through the old rotted fill pipe all the way under the floor up to the vent pipe. This lets the spew and fumes go the outside while filling. I can fill the tank at full pump speed without burps. last thing i did was locktited the old fill cap so no one would ever fill there again . Total cost around 35 bucks. About 6 hours. labor but some of that time was spent scratching my head, hope this helps I am new to this board and wish I had found it sooner. all good stuff. dave.

          Gents-

          When replacing a vent tube, I was told to always make it a bit longer so that you can make a loop in it right before the hull so as to prevent any suction.

              A loop in the vent tube? How does that work?

                I put the fill tube on the right side of the console about 2 inches dowh from the windshield. Used flex uscg approved hose to go directly from the tank to curve around and up to the fill assembly. dont forget to ground everything well. This is a very good work-around to a ugly problem. I did have to cut a 2 inch hole in the tank cover to allow the hose to come up through. this was sealed up with silicone. hope this helps,. will try to get pictures posted soon.

                  You should have a loop in the vent line so that if water is pumped up the side of the hull in a big wave and it goes in the vent line it will not go straight to the tank. It can make a big difference on certain hulls even though you slant the vent itself toward the stern as far as water in the tank goes. If the water gets in the loop it will not pump in the tank but evaporate.

                    This trick worked for me with my mako20, but should work with any boat if the inlet to the tank is located directly under the console area. Thought about that later some boats have a much larger tank and the inlet might be farther up. just a thought.

                      Hi Dave,

                      Been there, done that. Also replaced the entire tank in my 231 twice in three weeks. Boy, that was fun. Never believe a tank guy when he says he can repair an old aluminum fuel tank. When I was done I was a real expert at cutting away foam and putting in new.

                        HeHe It's a bunch of work to install and rip out a tank.

                        I go back to my standard saying " Just cause it's new, doesn't mean it's worth a damn". Preasure check the tank "YOURSELF" before you install it.

                        This will save a lot of headaces.
