My '74 Jimmy

Thanks guys for the response. I appreciate the help. A little update. I took the throttle body off and took it apart to see of there was any trash in it. There are two hard lines coming out of the back of the throttle body. Are they both fuel lines in? I put a bowl down to catch the fuel and turned on the key and fuel only came out of one of the lines (the one on the drivers side). Is the second a return line? I'm not real familiar with the throttle bodies. I really don't want to drop the tank if I don't have to so thanks for the advice. I wanted to take this on a camping trip in two weeks, so I'm hoping to get the problem fixed before then.
