This is in a 99.0 preface lift. Is the black power and brown the ground? I'm installinghttp://uploads.tapatalk-cdn.com/20160924/d20bf2bbf485a27ae61c502909e24b92.jpg my walbro 255 right now and have a black and red. Should I do the red from walbro to black? When crimping the wires together?

Black is positive and brown is negative/ground. Look at terminals on both pumps for the (+) and (-) for confirmation. If wires are put on backwards the walbo shpuld still run, but in reverse polaritym
