I picked up a free Cagle fuel regulator and have a few questions about it. It has a fuel inlet, fuel outlet, and fuel pressure gage outlet; it also has a fitting on the bottom. Is this fitting for a vacuum line? If so what do you connect it to? Also can you run an electric fuel pump with this regulator? If you can what pressure pump should you use, what is the normal operating fuel pressure for a '78 Jeep with the 258 inline six? Another question, how do you lean out the carb on this Jeep? Is there a jet kit or something to do this. My Jeep runs way too rich as is. Thanks in advance for any help.

The additional port is for vaccumn,and if memory serves me correctly it should go to a manifold vaccumn port.you should be able to use an electric street pump but I would avoid any type of high pressure racing pumps.the cagle regulator reduces the pressure at idle and increases under low vaccumn probably to about 6lbs.
Before you start changing jets install the regulator and/or check the float level,choke settings these things would cause an overly rich condition

Keep the shiny side up !

I recently rebuilt the carb, and the float level was set to spec. will lowering it slightly help lean it out?

Are you sure it is the right model Cagle? There was 5 or 6 different versions for different applications.

I still have my instructions if you want me to scan them for you. Just email me.
