Fuel Cell
Well I got my (fuel cell) figured out. Went with a 2 gallon clear similar to astrohog's 1 1/4 gallon.
It would not fit in the bottom section of the all so popular Box from Hell,so I took a hair dryer softened it up and pushed it into position PERFECT FIT plus its 2 gallon
I took a 1 gallon milk Jug lid and some blue silicone form a gasket and secured the bottom hole HOPE it works I will let it set a day or so before the test (ANY advice)
My cell will go in the bottom of the top
