I don't remember the year it all changed, but THE ONLY fuel filter on my 83.5
Westy from the factory is that square plastic fuel filter. It's before the
fuel pump--that is to say between the gas tank and the fuel pump.

That larger round metal canister fuel filter, as Dennis said, was installed
after the fuel pump.

Question I have is: don't we want a filter before the pump to keep crud out
of the pump? And then, on the newer models is the canister filter AFTER the
pump the only filter?

Best,
