I've been smelling gas off and on since I bought the car but couldn't find a leak anywhere. So... after seeing the comments about Walt and other replacing gas caps I examined mine more closely. The rubber was hard and brittle and had some cracks, so it looked prime for replacement. I could not find a cap at first. I checked O'Reilly (Irish name ought to have parts for an Irish car, right? :) and Standard, but struck gold at WalMart. :) Walt- I also got a Stant, but it is #11810; it's not fancy but it is a pressurized cap and fits snug and needs to jerry-rigging. Should that be in the Xref file? BTW- I am wondering if my cap was original for late '81 (and worth holding on to). It's just a simple black cap with the middle ridge to grasp and turn. No lock, nothing fancy. Is that original? Thanks, Kevin #4687 [Non-text portions of this message have been removed]
