So yesterday I took my van to a well known local audio shop to get a remote start installed as well as the kicker 8" sub installed. While in there, I had them install a dual USB port above the visor shelf for my dash cam and future rear view monitor. So all went well except when they installed the sub under the driver seat it was a tad too close to the right side of the inner seat frame causing a vibration when on loud setting. No biggie. I decided to just unscrew the sub and move it over but as I removed the screws which they installed (3" black drywall screws), I noticed a faint gas smell. Now at this point I was scratching my head why they first of all used, drywall screws and why 3"? I opened up the fuel pump cover between the seats and put in my snake camera and sure enough, there's the screw going through the metal floor board and into the poly tank. I called the shop and they told me to bring it to them on Tuesday. I don't know what they can do to fix, but it looks like a big job to drop the tank. Is there even a proper fix? Should the tank be replaced? I left it alone at this point.
