Spent a good part of the day investigating this gas odor. I checked the fuel pressure regulator vacuum line and found no leakage under pressure, checked all the other lines around the injectors all were ok. Did find a break in the charcoal canister line and fixed that. Also pulled the back of the truck out and replaced all the small gas lines on the gas tank. Still have the gas odor. I will go for a new gas cap next and see if that does it. Will post back when I can get my hands on one. Woody
