A D V E R T I S E M E N T S

About two months ago, when fueling my vehicle, I noticed a puddle of gasoline in the vicinity of the left rear wheel, inline with the fuel filler door. I had noted the check engine light subsequently came on and code 0440 (or a variant of that, I cannot recall with 100% certainty. When I had some free time, I started investigating the emissions code and decided to check the fuel system from the rear of the vehicle working forward. While looking at the fuel filler neck, I noted a glint of fresh steel behind the tire. Upon removing the tire, I noted a hole in the filler neck the size of a us quarter. Since it's a fuel system component, I investigated whether I could get a replacement part (to no avail). My field expedient fix was to wrap the fuel filler intake steel pipe with a copious amount of duct tape as a temporary fix until I could see if a junkyard would yield a new pipe. No such luck in find a part that didn't have a hole of sorts (see enclosed photo's of 'replacement' offerings. My investigation led me to conclude the wear in the pipe was caused by wheel hop, primarily when rolling over speed bumps at a speed higher than recommended, causing the rear wheel to "hop upwards" and come in contact with the pipe. Given the amount of speed bumps in residential neighborhood, the likelihood of this happening is consistent the location of the damage and the inner edge of the left rear wheel. I've enclosed pictures of a 'replacement' pipe that will have to be epoxied to contain vapors and prevent fuel spillage unless a pristine pipe is found. Given the emissions issue along with fuel spillage when fueling the vehicle, there's a high likelyhood of further damage and possible fire hazard. I'd recommend a metal shield be retrofitted to prevent contact from the left tire and the fuel filler neck
