Still don't know why, but my gas cap vent - didn't. Neither did the rest of the
system. Yesterday morning I was in my commuting mode, running along smoothly at
60mph, when all of a sudden the engine sputtered and died as I pulled onto the
shoulder. Sat there for a moment and pondered the world while listening to the
silence of 5:15 am. After about a minute of contemplation, I turned the key to
listen for the fuel pump. No sounds. Turned the key farther - engine fired
up. Said "sonuvagun", or something like that that, and pulled back onto the
highway. About two miles up the road it happened again. Pulled over on the
shoulder - got out - went around to the back and loosened the gas cap. THUMP!
You should have heard the sound of the tank sides expanding after the inrush of
air. I'm very impressed with the ability of that SU pump to suck up some
vacuum. Left the cap at the first click and continued on my way. Strikes me
that this shouldn't happen in a '77B with the charcoal cannister still plumbed
into the vapor separator. I'll check it out tomorrow.
