<VV> 110 WOWS!

[Paul Fox]

Wrong, mine did. I had put a gas cap on the tank while I was racing because the one on the tank was leaking gas all over the track. The cap installed was not vented and the tank caved in. At first thought I had ran over something but it was bent on top too. I never would have noticed it because the car ran fine. I only noticed it when it rusted through on the bottom.

I knew a guy who had a '69 Coronet with the wrong gas cap (looked 
more like a radiator cap) that failed to vent anything, and his gas 
tank "shrunk".   The engine never let on that it was starved for fuel 
or gave any other symptom of improper running but his gas tank caved 
in and did NOT pop back out.  Afterwards, his gauge never read 
"empty" before running dry, which is how he found out about the 
shrunken tank.   Of course, you likely have seen the tank in a '69 
Coronet and it's shaped more like a slab than a tank.

'69 Cuda tanks are like that, had one of them.   It also had a 
slightly shrunken look on the bottom, wouldn't show empty when it 
was, popped it back out by pumping a bit of air into it.   I also 
unclogged the cap vent, took a bit of work since it had that big 
chrome flip-cap on it that required some disassembly.    Looked like 
a mud dauber had been inside it.


Corvair tanks wouldn't likely collapse like that even if the fuel 
pump was stalled completely by a clogged cap vent.
