My '86 had both.  My '85 had only the inlet filter, so  I added the large
metal filter on the exit side.  Inlet filter is critical with old rusty gas
tanks.  Noisy pumps usually are due to starving of inlet or plugage
downstream.

Subject:  always a second fuel filter?

Speaking of the "suction-side filter," my vanagon (87, 2.1) only has the
Bosch filter on the high pressure side (between the pump and the regulator
/
injectors).  My interpretation of Bentley has been that some models have NO
filter between the gas tank and pump.  Am I wrong about this, and the PO
removed it?
Thanks,
Jim
