Fuel Blowback (aka BB Baptism) - Gary Miller - 05-09-2007 01:11 I can speak for certain that the FC's all have a fuel tank vent line. It can be seen protruding from the front, curbside, top of the tank, which is also where the wires to/from the sending unit are. The problem seems to be that the little vent line (about a foot long) was made of some type of vinyl or plastic material that, over time, has caused it to shrivel up and become useless. What it looks like is a black straw from a milkshake that a hungry kid has chomped on for the past 15 minutes. I suspect that, as the tank was filled over the years, this inadequate material was subjected to the fuel/vapors and didn't last long. Replacing it is nearly impossible unless you happen to have the access panel in the floor out for other work. In my case, I had the access panel open to install a new sending unit and plumb my new generator, so I replaced the vent line with a larger diameter rubber fuel line. It works very well. Barring this procedure, I have heard good things about the filler insert being able to prevent the blowback. The other nice thing about being able to prevent the pressurizing of the tank, and the foaming of the fuel, is that the tank can be filled more completely. Just information and opinion.
