Most likely one of the vet tubes or fittings on top of the tank failed. You
will likely have to drop the tank. Keep in mind if fuel is getting than rain
water and road debris are getting in. If this has been open for some time
the tank is likely rusting also. Try to fix this asap before you also need a
fuel pump and injectors along with the new tank.

Subject: Gas overflow

I'm getting gas coming out somewhere when I make a left turn. Its appearing
on the outside of the van from the gas cap area and downward.   It has been
too cold to do any work this spring so I have not taken a look at it deeply
yet.  I have an '83.5 but I have the later model "floaty ball" filler tube
that I thought was supposed to stop this.  Anyway, before I go taking out
the filler tube, etc. what should I look for and are there any particur
parts, gaskets, etc. I should replace just because I'm there?
I've tried multiple gas caps, its' not that.

Thanks,Bryan
