speedway .
I bought the fuel filler and cap from speedway drill and tap for screw on, , I tapped a hole for a compression fitting on the top. , 5/16 I think. then bought a new steel line at the parts store, cut the end at 45 * then drilled thru the fitting so the tube would go all the way thru to the bottom then up i/8 and tightened the compression nut...For a vent I got one out of a 70's ford pickup tank and drilled a hole with a uni-bit step drillbit for the ford grommet then pop in the vent
