If you presently have a line that runs directly from the pump to the carb, then adding the glass bowl filter (assuming you have a 55-9 Mopar) will involve redoing the fuel line. One of the easiest fuel lines to fabricate, it should take an hour at most. If you are thinking of adding an aftermarket plastic filter, you will also have to cut the line.

I'm not sure what your carb's inlet fitting is at the moment, but something like a Wix 33481 can do what you're desiring. It has female double inverted flare (DIF) fittings on the inlet and outlet. Put a female DIF adpater in the carb if it doesn't have one, make up a line with two male DIF nuts on each end that runs from the carb to the filter, and make up another line from the filter down to the pump.

Another option is something like Wix 33046 that has a 1/8" male NPT to 5/16" barb if your carb fitting is pipe thread.
