What 2003 Chevrolet Express 1500 owners say
Fuel & propulsion system
Corroded and leaking fuel filler neck. Foolish design involving dissimilar metals held in contact and surrounded with a conduit which holds water and road salt. Design is destined for failure. GM has a partial recall for the snow belt. Such a foolish design should be fixed everywhere as it is just a matter of time until failure.
On a few occasions prior to locating a leak, I noticed a gasoline smell. Finally when filling earlier this month, I saw a lot of leaking coming out of the fuel filler tube, between the metal tube and the plastic cover surrounding the tube. When I got home, I cut off the plastic tube about halfway and found a static wire running the length of the tube. Everywhere, where this wire touched to metal pipe, it was corroded completely through. The static wire is of a different material and was not corroded. Presently I have wrapped the tube with a gasoline resistant tape. But, I will have to replace the tube soon. The local dealership has quoted approx. $241.00 without installation. Are there other instances like this and is there a recall I'm not aware of. Thank you for your time.
