alcohol/methenol

although i start mine on alcohol it could be started on gas. see the red covered solenoid next to the accumulator, it's a nos gas solenoid. the #4 ss line goes to the hat with #70 jet to start it. i have a momentary toggle switch on the dash that opens the soleniod and starts a holley blue pump that feeds out of a 1 gallon plastic fuel cell mounted inside the trunk.
