I'm in the midddle of a complete redecking project on a 16' Alum. Tracker. I have 3 batteries and a 6 gallon plastic fueltank all of which will be at the far rear and in very close proximity of each other. I thought I saw here somewhere that one needs to exercize caution in this area, So I was wondering if I need to make a sealed area, tray or compartment for the fueltank and vent it somehow. One guy told me I need to installl a fresh air blower along with a vent system where the fueltank is stored, there will be a closed deck above it. I 'm not familiar with any of the safety aspects and would like input. I certainly want a safe set-up I just need to know what to be aware of and what I may need to buld in to this. What about any kind of trays I may need to build for the batteries and or fueltank ??
