First thing, fix the leak.

Yeah... bad wiring + fuel leak = bonfire. Fix the leak, then check the relay and all the wiring inbetween with a multimeter.

Sounds like you replaced the fuel pump with a high pressure unit, which is now overpowering the carb and pushing your fuel right out the exhaust.

Once you get that corrected, you probably need to perform a major deflooding and some new plugs.

What fuel pump did you use? If it is a high pressure pup Kentetsu's answer is the solution.
