“There was a strong smell of gas in the car as well as another vehicle who pulled me over to tell me my truck was pouring gas. After having it towed to my mechanic, he informed me that the fuel pumped assembly had rotted and need to be replaced. He stated that this part should not have rotted like this. Thankfully this was found before anything catastrophic had happened as I constantly driving around with my two young children in the car. I have kept the old part to show how it had rotted. …”
