B&S 25hp Intek v-twin

[bbbb]

i just bout this engine model # 445777 to replace my worn B&S 18.5. I got evertthing bolted and lined up, fits great. the problem is the wiring is diferent. the new engine has a plug with
a red and orange wire spliced together i will assume it is alt. power
a green wire running from the low oil cut off switch
and that leaves a gray and a black wire that are running from the carb. float bowl.
the engine cranks and has spark, it will run if i pour gas down the carb. but the fuel pump will not work, i am assuming that it has something to do with the black and the gray wires running from the float bowl.
any ideas out there
