Today I put gas in my car at a gas station for only the second time. The gas filler is behind the license plate. Haven't had a car with this configuration in over 30 years. So, what idiotic thing did I do today? Yep, after pouring in some ethanol treatment, then pumping my gas, and trying to be meticulous about the process, I forgot to put the gas cap back on the filler neck.. I left it sitting in the trunk pan, and closed the trunk lid..
I cranked the engine to leave the station, and it backfired through the carburetor (first time I've ever heard it backfire). Cranked a second time and it started up, but sounded weird. Carb was making a loud sucking noise, that I'd never heard it make before. Made one lap around my neighborhood then drove home. Pulled in the garage, opened the hood, and heard this weird sucking noise coming from the carb. Shut the engine off and wondered what the hell was causing this. I walk to the back, open the trunk to retrieve my ethanol treatment bottle, and I see the damn gas cap sitting on the trunk pan.. And figured I just found out why my carb is making strange noises?!?
What do you think leaving the gas cap off did to my carburetor, and or fuel system? I have the Hemi style fuel separator/filter with a stock mechanical pump. It was getting dark when I got home, so I've not had a chance to run the engine, or drive the car, after putting the cap back on. I'm just wondering what terrible things can happen if you stupidly leave your gas cap off on these cars. I think this is the first time I've EVER done this. Never did it on my Challenger. I'm not used to the gas behind the license plate, and frankly I don't like it located there. I'd rather have it on the quarter panel.
