One of the things I did at work today..., Found an EVAP leak. Options

So for those who are not familiar the EVAP system is part of the vehicle emissions system for pretty much all cars these days. can't name one car in the past 20 years that does not have evaporative emissions controls. how the system works is the gasoline vapors are trapped in a canister filled with charcoal carbon and then under certain engine conditions the canister full of vapor is purged into the engines intake. the engine from time to time will pull a vacuum on the whole system, close some electronic valves, and test that system holds a vacuum. if it does not then it can determine from how fast vacuum is lost if its a large or small leak. How we test at the shop for a leak is by pressurizing the evap system with about 1psi of non reactive smoke and then looking for leaks with the various solenoids and valves all closed up.

This particular car is a 2001 Mercury GrandMarquis GS, same thing is a crown vic and some other lincoln model and has a P0442 EVAP Small Leak. the fuel tank rests in a 'hump' behind the back seat and infront of the trunk tire well. this creates a shelf in the trunk which is an awesome place to mount your amplifiers for your ghetto sound system. now the fuel tank is literally less than 1/4 of an inch below the sheet metal in the trunk shelf. hopefully with this explanation the below picture makes sense and you can all see how this guy pretty much bent himself over and ****ed himself. :lol:

5 dollar gas tank repair puddy will fix that problem. did not really bend him self over that hard.

we can't use $5 gas tank repair putty, should it fail, leak, and then the car catch fire we'd be on the hook. he'd need to do that repair himself...and the fact that he put a screw through his gas tank i highly doubt he has the skill set needed to drop a fuel tank without making things worse for himself. not to mention theres another amp mounted right near that hole, don't know if that one punctured the tank too.

he's getting a used fuel tank from an auto recyclers.
