Yea I know what it says. But if something says, not to be used in fuel, and you put it INSIDE the fuel tank, you're asking for trouble over time. Would it work for a while? Sure. Would there be a serious risk of fuel hitting it over time, swelling the wires and breaking down the connector, you bet your ass. I've seen people use non fuel safe wire on walbro installs only to pull them out in a few thousand miles and the wires are like gooey mush. Fuel gets on everything in there. How do you think the fuel ends up on the outside of the fuel pump cover necessitating the need for a sealed connection?
