I recently topped off my 2007 RAM 1500 with the 3.7L engine and the next day discovered gasoline streaming from a line near the front suspension. Initially I thought it was a fuel line, but later discovered it was a vapor line. When I had the truck towed in, the dealership said the entire vapor recovery system was filled with gasoline; that they drained a couple of gallons out of it. Has anyone ever heard of this happening? They want to charge me $3500 to replace the vapor lines, but can't tell me what failed. Seems like it could happen again. Note: the truck had "X49 - Extended Warranty - Fuel Tank Inlet Check Valve / 2007-2008 (DR) Ram 1500" performed about 3,000 miles ago.
John - thanks for the reply. I always end fueling when the nozzle clicks off (a habit I learned when filling a 35 gallon tank at $4.25 a gallon!), so my thought is, if you fill a tank when it is cool and it then sits in the sun, the volume of the gasoline expands. Where does it go? I suspect into the vapor recovery system, but what would that path be? If I could determine that, I could probably find the failure point. Also, does it make sense that they want to replace the entire system? Why not find a failed valve and just replace that? Can't the rest of the system be purged with air?
Not familiar wit h the truck, but usually when/if the canister gets fuel soaked, it needs replaced. The lines to and from it aren't made for gas/liquid, so they need replaced. I suppose there could be something causing the system to suck raw fuel. Ill look later and see what I can come up with.
Just another reason I stay away from Chrysler products.
