The 133-133-511 is the standard filter used on the early tanks with 7,,
hose outlets. The 1HO-201-511-A has 11mm hose inlet and outlet. It was
installed on some 86+ vans to catch new tank debris. It was to be
removed at the first service and only the metal filter after the pump is
used.

There is a screen or sock in the tank that will catch the big stuff and
protect the pump. There is little benefit to a filter before the pump
and most manufacturers do not use one on FI vehicles. A filter can cause
more problems as the fuel will vaporize or boil under a vacuum and these
pumps move a lot of fuel so restrictions before the pump must be
reduced.

Subject: different fuel filter #s for 83.5 Vanagon

Does anyone know the difference in the in-line fuel filter both listed
for
the 83.5 watercooled Vanagon?

The one in the bus now is a square plastic filter just before the the
fuel
pump. (The 83.5 does not have a metal filter after the pump like the
84-85.)

ETKA shows 2 filters:

1HO 201 511-A
133 133 511

And there doesn't seem to be any distinction listed. Will they both
work,  or
are they for two different set ups?

Thanks
Jeff
