complete kit includes unused fuel pump, regulator, o2 clamp on bung.
just had it running 3/12 but had too much rfi and i didn't want to change out the hei distributor setup. would probably work better with a msd setup. upgraded to the ver 2.1 which is much better then the earlier versions. price is plus shipping. if you don't have the cash don't bother trying. shipping probably approx $30 from 66071 box approx 18 x 18 x 18.
