Well, just finished installation of an Airdog on my 02. Took the bed off since my tank was 3/4 full. Only 6 bolts, ground strap, couple of light connectors and the filling door connection. took 20 minutes tops, 4 people can easily lift it of the truck if you have to do it the old fashioned way. Took the fuel module out and it looked pretty good, very little stuff in the bottom screen. Very impressed with the quality of the Airdog, nice clean design, very quiet, all fittings tyraps, hardware etc. all double bagged and organized with very good instructions. Quality American product, very happy with results. decided to leave factory fuelfilter/heater/WIF sensor in place. Would recommend to anyone.
