Sons of bitches....
I figured that it had something to do with the tank being an older car, that the fumes backed up and caused the pump to shut off.
21 gallons? Damn thats big. Maybe thats late 2nd gens? Im gunna snoop around Nasty and find out, do a little search.
And I gotta get a haynes manual for the car. I have 2 vaccum lines that I dont know wtf where they go to, but they werent uncapped before? One is a line from the carb, to a T fitting that is attached to the PCV valve, and the other side of the T fitting has nothing...and then there is another smaller vaccum line that is just open, no idea what that does. There is also something attached to the bottom of the air cleaner that looks like there needs to be something there.
