I THINK your '67 originally came with a filter built into the fuel 
pump. VW never used an inline filter anywhere with the carbed 
engines.

The gas tank is high enough that it will supply sufficient gas to the 
carbs, even if the stock fuel pump is bypassed, as long as the tank 
is half full or more. So you might want to see if you have the same 
problem on a full tank. If you do, your problem is not vapor lock.

It may be that all the gas in your carbs boils off in the heat soak 
after shutdown. If that's the case, you should check to make sure all 
your cooling parts are in good condition and that the bakelite 
insulators are in place between the carbs and the intake manifolds.

If you still have the problem, you can cure it by bypassing the stock 
fuel pump and adding an electric pump under the gas tank. If you do 
that, you must also add a crash safety switch. There's a common Ford 
switch available from NAPA dealers for a very reasonable price. 
Someone else here should be able to chime in and give you the part 
number.
