flynlow8740 Posted June 17, 2014 Share Posted June 17, 2014 I don't know anyone with a B to compare to. My truck is missing the fuel cap. A modern cap won't work as it appears to be pipe threads. Is it a standard pipe cap with a vent or can some one show a picture of their cap? It's the 70 gallon square tank.
