The more I do on this Jeep the more questions I have. I was checking the fuel pump and noticed that the two outlets have been plugged off (see pic). I'm finding a lot of modifications to this ole gal! HA I'm confused with this. These are for vacuum lines correct? I've been reading the service manual and one of these lines should go to the carb and the other for wipers? All I see on this particular modification is an "In" with an inline fuel filter. The "out" goes to the carb itself. Can someone school me on this? Also, if those two outlets are not being used, can I replace the fuel pump with a single action unit?DUAL_PUMP.jpg
