I have moved on to making the jeep more drivable by making it not reek like gas. Here is a wonderful description of my redneck gas system
Whats killing me is the smell while driving it. Reeks like gasoline, and if i roll down the rear window, it reeks like exhaust (duh), so i'd like to eliminate the gas smell...well, i did some research.
FYI I'm running an after market rear fuel tank, jeep is set up for an auxiliary tank, the stock one was removed because they thought it was dirty, and everything was just hooked straight to the aux tank. I have an electric fuel pump connected to nothing, and a valve on my floor to control the tank flow, but basically its the stock set up all run to the aux tank....anyway...moving on...
Seems like a saturated carbon canister or whatever can cause this to happen. That was my first stop! Pulled it out, disconnected the two lines labeled "tank" and "carb." The carb line was going to a 3 way vacuum fitting on the brake booster, so i figure that was okay...other line went back towards the gas tank.
Well, the canister is open on the bottom, and it smelled fine. a little like engine, but i didnt get a nasty gas smell like it was soaked? Moving further down the line...
I start to discover the WONDERFUL bubbatized nature of my fuel system...they apparently welded a fill pipe so the gas flowed into both tanks. After removing the stock tank, it was pinched and welded shut, so it just goes into the aux tank.
now we see the red line running into this little box, with 2 black lines that I assume attached to the vents on the original tank...but now they go nowhere. we also see how the actual fill nozzel and the blue vent line for the aux tank just vents INSIDE THE VEHICLE, behind this poorly attached panel. So, that explains why my quarter panel was pouring gas from the inside when I over filled it today.
the red line that runs to the canister is attached to nothing technically.
Plan is to correctly connect the breather line to the fitting on the fill neck, and then run a vented gas cap for a bit, until i reinstall the stock tank and can utilize the carbon canister system correctly. Woohoo! Should be an easy fix if'n ya ask me. Hopefully it wont reek inside anymore.
