I forget what vehicle it was now, but first learned about the hit the gas tank thing in a Five Guys parking lot. They were parked next to me and couldn't get it started. I had my tool bag with me, but no idea what was wrong. Had recently hired a guy who had several years experience as an auto mechanic. I sat in my car and called him and he told me 'hit the tank'. Came back and hand the guy a hammer. "This is all you should' need. Looks at me like :wtf:. Couple taps and started right up.:rofl:
