[QUOTE="FW_Z71Burb, post: 29058, member: 13704"] Started smelling a faint fuel smell last couple of days. Mainly coming from drivers side. Not constant, typically after driven Wife also reported issues filling up and pump clicking off with the set the handle method, worked when she held the pump. Filled fine for me last time I filled up. I also saw this under the truck yesterday, crawled under there and can’t really tell if it’s oil and water or gas. Coming from underneath the front differential area / skid plate / cross member where there is some oil residue. It’s also been very wet and rainy here in Texas so I think there’s more moisture down there than there was after I got the oil leak fixed RMS [ATTACH type="full" alt="IMG_3064.jpeg"]6169[/ATTACH] Parts replaced last 8k miles - AC delco fuel filter - AC delco fuel pump - AC delco fuel cap Checked all over the fuel lines and pressure regulator and don’t see any signs of leaks. I just checked the solenoid on top of the intake manifold and it’s a DELPHI P/N 737312 [ATTACH alt="IMG_3065.jpeg"]6168[/ATTACH] I’m thinking it’s an EVAP system related issue but it’s not throwing any codes. Any other things I can troubleshoot? [/QUOTE]
