that'* not safe

Why'* that?

Flick yer Bic and find out...

I'm not sure why, but it just isn't, gas could spill?

Gas in liquid form isn't explosive, Fumes, on the other hand, blow up quite readily.

Both are dangerous, bt just imagine if the cap felloff, I know it is behind the license plate, but still

That'* why I wasn't worried, because its behind the plate. And, remember its the old type of cap, where you line up the two tabs into the grooves, then twist, like a radiator cap. so I think it is less likely to fall off.

you should sitill fix the vapor line, that shouldn't cost much

Actually, the car is going back tonight. :( His wife is coming to pick it up. I believe she is taking it to have the heater core fixed. (Didn't know anything was wrong with it) I'll recommend they look at the vapor line.
On a plus side, in exchange we'll be receiving his Lumina APV in exchange, so that works for me.

Don't forget to tell them about the AMC Eagle Nest
