First, the basics (just in case...): Fuel filters, like oil filters, are
designed to flow one direction. Check the filter for an arrow -- this
shows the direction the fuel should flow (generally the arrow pointing the
flow to the fuel pump). Other than that ya got me! My T3 originally had
FI so the filter was under the tank. With carbs the current filter is at
the carb end (but I'm hoping to change that with a better filter).
With the info given (and the filter properly installed) I can only think
that the filter is too restrictive for the mechanical fuel pump, thus it
can't properly draw fuel from the tank or it's sucking air from a loose
fitting somewhere. Try using a FI fuel filter. If you are using a fuel
pressure regulator either remove it or increase the pressure setting.
Any particular reason why the filter needs to be located in a difficult
spot like the front of the car?

Hi All,
This doesn't apply specifically to type IIIs but there is a lot
better info from you folks than the other VW list so I hope you don't mind.
(it could happen to your type III also) A friend of mine just bought a 71
Super Beetle and I've been helping him get it running. We installed a fuel
filter at the tank and then it stopped pumping fuel to the motor. We removed
the filter and everything worked fine. I've had two filters (one at the tank
and one at the carb) on all of my VWs including my type III and never had
problem before. Anybody have any ideas?
