That's a good tip.  A good example of an unexpected hazard.  Sometimes you
really have to think these things out.  Hope I will remember this one for
future ref.
I remember getting drenched in gas while pulling the engine on my '69
Westy.  IIRC, the fuel line just crumbled when I tried to clamp
it.  Reaching up to try to stop it, the gas ran down my arm, soaked my
clothes, got all over me.  I wanted to both jump out from under the van and
also stop the leaking.  Way too much fuel in the tank.  I finally gave up
and ran to get pans to catch the fuel as it drained.  I ended up with about
5 gallons.  That is a pretty terrifying feeling to have gas all over you.
