What I'd really like to know is how this part works with gasoline, 
installed on your car. I did my test with Diesel fuel, which I 
thought should be LESS aggressive than gasoline, but when it failed 
that test I didn't go any farther. I'd like to know how it actually 
works out in practice.

The people at ISP assured me that they'd never had any trouble with 
them, but it seemed likely to me that they had never done any 
followup inspections, and I didn't get the impression that they had 
ever done any kind of compatability test like I had done. Plus there 
was the problem that it couldn't possibly be the right length for 
both early and late versions.

Early versions are longer and fit '68-'72 with the quarter turn gas 
caps. Late versions are ~3/8" shorter and fit '72-'73 with the 
screw-in gas caps. The difference arises because VW had to move the 
side port on the filler pipe to accommodate the longer screw-in cap.
 
My kits fit either version, because you have to cut a hose for proper 
fit in your car.
