My '76 FJ 40 has been running rough and smelling like gasoline for some time. Finally the smell got real bad and I found a fuel leak in the line that runs to the charcoal canister. I replaced all the lines with new ones, but now the truck won't start. It acts like a car after it's run out of gas. I took off the air filter, and dribbled a little gas into the carb, and it will run for a few seconds, and then dies. If I keep dripping gas into the carb it will keep running, but it won't run on its own. I've done this about 30 times, but can't get it to keep running. The truck was running when it was leaking fuel, so it's not an issue with the fuel pump, the filter, or lines that to and from those items. The lines and filter were replaced a few month ago, and are fine. Why was there gas leaking out of the line that goes to the charcoal canister? I though it was only supposed to handle fumes. One of the lines I replaced had a right angle bend in it, and I couldn't put in a new piece of line without it crimping. I added a plastic tee that I got from a hardware store (see photo), but it has a smaller diameter than the 5/8" line. See drawing. Could that be why it won't run? What is the purpose of all those lines, and what is the purpose of the metal fitting the 5/8" line runs to and from? Any advice will be greatly appreciated.
