i tee off the existing line going to the fuel pump, add a short nipple to the tee bottom and a 1/4" ball valve with a pipe plug in the valve. if i have to drain the gas it goes right into my gas can. should i need some gas for one of my other gas operated engines during the winter for the atv, snow blower, generator i take it out of the trucks. i fill the tanks in november and start running them in march. weather permitting ill run around on a nice day to cycle it through. i use no additives and havent had an issue yet not to say that i cant or wont.
