Doesn't work
"Bought this for a 2004. 5 Duramax. Fitting at the injection pump is wrong. The fitting that feeds the injection pump this line is replacing. Comes out of the back of the pump and points towards the firewall. This line comes from the passenger side and down to the injection pump. In order for it to work. It would need a 90° fitting to attach to the injection pump. I tried to explain this problem to diesel power. They gave me the number of the company that cuts the hose and supplies the fittings. I got no where with them either. They just said it's supposed to work. Don't waste your money buying it."
