    I found the TSB that supersedes the summary you found (just updates the model years) via my public library online. I parked a copy of the TSB on my CarSpace page. Hit Answer this Question to reply if you can't view it for some reason.

    Thanks for the detailed TSB. This van was apparently driven on dusty country roads, and the vent system might well be plugged with dirt. I followed the hose back to the canister, where I see a mirror image of the diagram but more complex --the hose enters the canister at the left, then exits the other end into the separator, then on to a smaller electronic component ( the canister vent valve ?), then on to a rectangular black box, then out the hose that vents to the air. Guess I missed it but surely there's also a vacuum line back up to the engine?

    I'm stumped at removing the plastic hose connector at the canister inlet ( my older E150 had no such ) -- is there a trick or special tool required? I bought the only manual I could find (Haynes), but it doesn't cover the evap system. Can you point me to a more detailed source of repair info for this van?

    In the meantime I'll try straightening the kink in the filler hose.

    I use the links in the Online Repair Manuals Guide, especially the Auto Repair Reference Center database my library subscribes too. But the links can be hit or miss and some make/models have better coverage than others.

    Maybe someone who's a real mechanic will weigh in.
