I've got a carter P4070 on mine(I think that's the PN...) An electric pump is a great improvement over the stock mechanical pump.
As for an arcticle, no real need. Mount it wherever you want to, so long as you can easily plumb it into the feed line after the tank selector switch. Personally, on the frame rail under the cab works for me. Hook it to power and ground. I have mine running through a relay that is switched with the key, and has a toggle to interrupt that.
I bypassed the mechanical pump by cutting the hard line about 2" below the fuel heater, and attaching the hose that ran from the hard line on the frame rail to the mechanical pump to the hard line at the fuel heater. Then I yanked the mechanical pump and made a blockoff plate for it.
