I have recently installed a 27 Gallon Pate tank on my new Montauk. Has anyone had this problem? I filled the tank on Sunday before putting the boat away in the garage. Monday morning the garage was filled with gas fumes.There is no leak in the tank. The gas cap I understand is self venting. Could the fumes be coming from the cap as the gas expands?It doesn't happen when there are only say 18 gallons in the tank.Should Pate put a warning on there tanks to leave two gallons short when fulling to allow for expansion?


Has anyone had this experience? I checked the fittings on the top of the tank and they are dry.Also seems to be some fumes from the motor area, however that is not for sure as I was smelling gas everywhere.

I've had the Pate tank for several years. One thing I quickly learned was to leave it about 2 gallons shy of full or else you will get fumes and possible overflow. There will always be some fumes, but you can dramatically reduce them by not filling the tank to capacity.

Same experience as Don. Don't fill it all the
way.

I've had the same experience with my 27 gallon tank under my seat, but my boat sits in the driveway in the sun. I found that the vent was plugged on the original cap and had it replaced with a cap that has a screw in the top to release the pressure when the gas expands, -sort of like the gas can you keep for your mower when its out in the sun. If I accidently leave the screw vent close you can see the sides of the tank billowing out from the pressure of the expanding gases.

I don't understand why a Pate tank, and no others, would create this problem. For years I stored my Nauset, often with almost full twin 12 gallon Tempo tanks under the console, vents open, and never noticed gas fumes.

I store my 18 Outrage, with a totally full vented tank, 63 gallons, in a closed garage and also don't get any gas fume smell unless I'm right in front of the vent fitting.

Could it be something else? The engine leaking fuel?
