Its a 1997 F-350 7.3 diesel automatic (that is junk) and a 10' flatbed.
Got the tank brazed yesterday, ---- I'm still alive,--no fires in the process. I stuck the air hose in there and turned it on half way to blow the smoke/fumes out. worked great. still had about a gallon of fuel in it that didnt come out but it didnt burn.
Hope today to put the tank back under the truck.
pix. of the mess! lol!
