So here's the latest. I used a compressor and blew air through the steel line. Fuel comes out of the pump and to the steel line but for some reason is not going through the steel line? I don't get why.... I know air is getting through cause I put a rubber glove at the end of the line and it blew off.... but... fuel is not getting through. Not even a dribble is making it to the filter.... what the heck am I missing???...what else besides air can I try to run through the steel line?

Do you have a MityVac that you can connect to both ends of that fuel line to determine if there's a restriction in the line that you might be able to monitor as basically backpressure. If there's very little backpressure, maybe your fuel line has a good size leak somewhere (that I think you'd see leaking with the fuel pump connected. But if there's very little backpressure the line could also be free flowing and the pump just doesn't generate enough pressure to push fuel to the filter. If you have access to a master fuel injection test kit you should be able to rig up a means to measure the fuel pressure at the fuel pump. Your local auto parts store might even have the master fuel injection tester available through their loan-a-tool program.

Alright! Dropped the tank and come to find out the line was pinched causing it not to put out enough fuel. So, fixed that. Now it runs!!!!! Yay!!!!! But..... smoke is coming from under the engine at the exhaust.... no yay.... now I'm out of my element completely and have no idea why smoke is cominh from here?

Congrats on finding the fuel line restriction!

Does the smoke have a distinct odor of either burning oil, burning leaves, burning coolant, burning plastic, or some other distinct smell? I don't really see anything that looks like smoke in the photo above.
