With this being a '72 250, it has to have points if its still stock. The only thing in the distributor is a set of points and condenser, I suspect thats what his " modual " was.

John, don't put a fuel filter in front of the pump, they don't like to suck threw them very well. Buy a new steel line and install the filter after the pump or right at the carb. I would put it up where it was easy to get to, you might be changing them out for awhile. The carb should have a bronze filter or a paper filter right in the inlet. You should replace it before installing the new line. Use a 1" wrench and unscrew the carb inlet. Replace filter and don't over tighten the fitting, infact, start it by hand very gently. You don't want to cross thread now!
Glad its running and didn't take long to figure out, Joe
