The P0440 has popped up twice now, The first time it popped up I re-seated my gas cap and cleared the code. Now it just popped up again, any ideas?

Could try a new gas cap. If not look over the EVAP system carefully. See if any of the hoses have come loose.

  Are those part numbers for a stock height truck? Thanks for posting the video.

  I have pictures of the 66, the starfire maybe the 72. I can’t say too much. We have lots of pictures of the first born. Not many of the second. Lots of the third my name sake. Mainly because of sports.

  Thank you newdude. The truck is getting a new 9.5' Fisher V plow installed by the local Fisher dealer next week. The truck has keyed ignition. I believe I have located the correct upfitter switch kit (85866211). As for the dual battery upgrade I am trying to figure if I should go with OEM or an aftermarket isolation system. I can't seem to find anyone who has added an O system to find out exactly what part numbers I need and if it is genuinely plug and play or if wiring changes are needed and if so what.

  Don`t have any pics of my `77 Cutlass Supreme that I sold to get my 2000 Silverado 1500. Was a nice car. Maybe because it was mine.😉
