hey guys i need help i have a strong oder of gas coming from the passenger read side of the truck. i have checked the lines and the tank doesn't seem to be any thing wrong. ands also my oil temp, battery, and brake ideot lighs come on, stay on for a while then go off then once in a while they flicker, checked the grounds seem to be fine also. i have no idea any pointers.

 

Did you lift the back seat & pull out the access panel to the fuel pump connection? The fuel lines have a history of rusting out where the anti-rub clamps hold them in place, and there is one back at the top next to the tank. Here's what happened to mine recently when I had to drop the tank- the line was really corroded. I snapped it trying to undo it, even while bracing both lines & using line wrenches.




Also- Are you using the right gas cap?

 

I'm having this same problem, I just brought my truck to the repair shop so I will find out soon what's wrong with it. The mechanic said it was probably the fuel lines. I will post the problem when I find out.

 

That's what happened to mine, when I got it fixed my gas mileage went from around 12 to 20!

 

I too get only 12 mpg, and I too smell gas (except I do so when I'm standing by the rear passenger side door, near the gas filler cap door).
PLEASE tell me I too can get 20mpg!!!
Seriously, can you tell me exactly what made you look under the seat and not elsewhere? If the line ruptured there, can an equally old line do so somewhere else on the truck. Any suggestions as to where I might begin?
Thanks!

PS I'd be ecstatic with 16-18mpg!

 

thats where I smelled gas too, you probably have a similar problem
