I began to smell gas near my gas tank. Upon further inspection, I noticed there was gas leaking down the side of the tank. I then tilted my truck bed to look at the leak from above the tank and I noticed that the plastic piece connector coming out of the fuel pump housing to the supply line was pumping a stream of gas all over the top of the tank. I went to disconnect the hose and the plastic piece broke instantly fully cracking apart. Thankfully this was in my driveway and not driving as this would have been very dangerous. There was no warning light and this would have sprayed fuel everywhere, especially at speed. There are hot parts all over there and would probably resulted in a fire, and at the very least the truck to shut off while driving. I did not take it to a dealer as the damage was extremely obvious. …
