Just did this two weeks ago. The racetronic instructions are good. Be sure to wire the hotwire starting from the back (tank) because it's almost no way to feed the wiring with the relay connector from the front first. I jacked the back up on stands and dropped the tank out by hand but you need a floor jack to put it back in and an extra set of hands would be nice too, but I did mine alone. The only thing I think can be done is taking the rubber fuel lines off from the top of the tank and not up against the floor of the car like suggested. Go ahead and take off the hex head screw that holds the line to the floor but then drop the tank down and take the line off the tank. It is eaiser to work them off from there rather than up in the floor over the axle with all the crap falling in your eyes. Some of the early 86s had terminal connections and you have to splice in the wires others have an adaptor connection. Use the rubber sleave around the pump from the stocker and get it snug to the pipe going down. This will help the noise, mine is quiter than the stocker. Also it should tell you not to use the pulsator, you just use the piece of straight fuel line with the hose clamps to take up the space. Get um tight as pumping the gas back in the tank is not what ya want. If ya didn't know you can take the schrader valve out of the end of the fuel rail, put on a piece of hose to a gas can, put 12v to the wire behind the alt and pump the tank dry. Since your not going to reuse the pump you can run it dry to drain the tank. I added a T to the rail for a pressure guage line.
