My car stinks!

I suspect there's more to your problem. Stuff inside the tank should not be making smells noticable inside the car because it is pretty well sealed, except for the small hose going to the charcoal cannister and PCV, and if its an 'L' model, the large hose that connects the outside fill vent to the tank. It's pretty common to have this large connector hose rupture, and that would make smells. If I was you, I'd replace 100% of the rubber hoses on this car anyway- fuel, brakes, water and heater- before something old lets go and causes grief. The only other thing that comes to mind is rust perforations in the steel tank itself. Such things can be fixed but the tank's gonna have to come out firts, and that means the engine & tranny must come out first- not a pleasant task to do by yourself.

Thanks for the info. I replaced all the break lines, coolant hoses, pressure and expansion tanks, fuel lines, etc already, but I didn't know about the line coming from the fuel tank. I will check that out tonight and see what's up. I also read that you could reconnect that line to the engine intake manafold? Is that correct? Thanks!

The hose in question is to the charcoal cannister, which if stock, is so saturated and varnished after 30+ years that its useless. New cannisters are available. The hose arcs over the maintenence hatch in the rear firewall, just below the rear window. I wouldn't attach it to the intake manifold, as the vacuum there is much more than you need and could affect your mileage. Besides, you REALLY wouldn't ever want to experience a backfire in the intake..... Instead, the hose can be hooked directly to your air cleaner base using a small Purolator air cleaner filter cartridge for much the same effect as the charcoal did- outgas fumes get burnt up instead of landing in your cabin, and you are insulated by the Purolator filter from backfires torching off your fuel tank.

If it really does bother you, summit racing sells, of all things, a "smell good" additive for your gasoline! Bannana, cinnimin, pina-qalada, strawberry, etc. etc. I don't know about the actual effect on the engines' rings, plugs, valves and all that. Marlin.
