Please see picture. When I bought boat from previous owner he told me this was an additional fuel pump to help with extra humidity conditions in places like Florida. I took my boat to a local repair shop to have some unrelated things checked out. They commented on this item and asked me it's purpose and stated they felt like it was a fire hazard and that there was an extra strong smell of gas. I have no gas leaks. I'm just used to the smell I suppose. And for all I know it's no worse smelling than other boats. I have no idea if it contributes to more efficiency in some way, if it's a hazard, or if it's unnecessary and one more thing that can go wrong. After those recent comments I figure I should look into this. I have a Suzuki 250 ss. I thought about posting this in general bassboat topics but figured I'd ask Suzuki crew first. If you know someone who may be knowledgeable on this please tag them or send them to this forum. Thanks as always.
