I just replaced the water pump and everything SEEMED fine...now all of a sudden I'm not getting any fuel in the carburetor. Did I mess something up that bad??? The fuel line and fuel filter were replaced in the spring when I got the Jeep running after it sat for 6 years. Pretty sure it's a mechanical fuel pump. So when I push the gas I'm not getting any fuel squirting into the carburetor. And yes, the tank is full. Ugh. Help!
