... I'm pretty sure that I've got one on the '88 5kQ. I wouldn't necessarily
worry about changing it that regularly as long as you are using quality gas.
If you do decide to change the filter I'd recommend running the tank as close
to empty as you dare to maximize the amount of crud in the tank that gets
sent to the filter. There is also a screen at the inlet to the pump as well,
if you're in there changing the filter you might want to make sure that the
screen isn't clogged too ... the word I've heard is that having a dirty
screen/prefilter can contribute to noisy fuel pumps and premature failure ...
The only related problem that I've had was that my '78 Fox GTI has a screen
inside the fuel tank. I was having a problem where the engine would stumble
and lose power under acceleration when the tank got below 1/4. I replaced
the screen and resolved the problem ... the interesting thing is that upon
visual inspection the screen did not appear to be clogged ...
