I'm poking through the fuel delivery system right now, seeking the cause for the start/stop syndrome I had to deal with last week. One area I'm looking at is the fuel filter setup. On my van ('84, 1.9L) the arrangement is like this: gas tank > small square plastic filter > fuel pump > large round metal filter > ring line As shown on Bentley 20.26 I read on the Bus Depot web site that, "Some 84 and older models still sport the small capacity square plastic filter. VW determined that the flow was restrictive and upgraded to the larger capacity metal fuel filter for later years." And they sell adapter kits, one consisting of a simple 7mm-to-12mm adapter that lets a fellow bypass the small square plastic filter, to one that replaces it with the metal type. Which seems like it would put one round metal type before the pump, and one (the existing one) after it? To heck with all that -- what's the good setup for fuel filtering? -- Jack "Rocket j Squirrel" Elliott 1984 Westfalia, auto trans, Bend, Ore. |
