I took the line off the fuel filter output (to petcock) and it still didn't flow. I took the line off the filter input (from gastank) and there was fuel there. I just don't understand, I just replaced the petcock and filter. The ONLY thing is it's a little bigger than the old one that was on there. I even took the vacuum line off the intake manifold and sucked on it to see if I could get it flowing....
