Well I got a fuel/tool box combo from member cbrahs aka high desert ravelco...and got it installed with some secret plumbing.... Here's a question for some of you fellas... I plan on tappping into the stock system so the delta tank will gravity feed into the stock tank.. How would some on you guys do it and do I have to worry about tank overflowing?? I know it won't come out of the cap because of the valve in that but anywhere else???
