Most 71 owners have problems but not 72s... Is the Stant #10571? Get some measurements of your filler neck, depths & diameters as it relates to the cap, & I will compare to mine...
I purchased a neat little cap at Autozone, # 5771, for $11.00 that works nicely.
Thanks Bullit...I will measure mine....ddidnt seem like the diameter of the hole was the issue....it just wouldnt click locked no matter how hard I pressed it on.....Lined up the notches with the tabs on the cap and pressed and pressed and pressed....no joy....Same with the 70-71...I actually got the 70-71 stuck cockeyed on the tube.....no way that one was working.
I dont recall the number, but it was whatever stant listed for my 72.
Then the counter guy had me try a cap for a 70-71, thinking maybe I somehow have that year filler tube.
Nope.
Now I am wondering if I have "something else" filler tube wise, but that doesnt seem possible either.
Right now, its a twist on type cap and it fits fine.
72rtchallenger, thanks for the link! Bidding is up to $15 plus shipping already.....and no guarantee it will fit......
