Gas odors

[Ferdinando Di Matteo <ferdinando.di@domain.elided>]

Godfrey, the implosion  you had of the gas tank was caused by the plastic
check valve being stuck shut and not allowing air to enter the tank as you
burned gasoline.   The most simple solution would be for you to put in a new
check valve which will not allow vapors to enter the atmosphere.  Every time
you gassed up you got an inrush of air whenever you unscrewed the gas cap. 
That was the tipoff for you to investigate and prevent the implosion. 
Another check valve that occasionally sticks causes a pressure buildup which
creates a very dangerous condition.   That's the metal check valve just
abouve the plastic one.   Re-routing the hose is not a good idea.  Fred Di
