AH, the check valve, that lil $4 beauty is under the damn air box outside at the vacuum canister, over the wheel well, leaving you 2 options, pay Ford $1700 to repair it, they remove the entire heat/air unit to access under it, or cut a hole in the wheel liner. Be careful not to cut anything important. LoL

FWIW I'm about to dig into replacing my washer fluid bottle and that requires battery and tray removal. By the time its all exposed I'm of the belief these fricking vacuum reservoirs, hoses and check valve will be exposed (or close) to it by then?
If so I'll post plenty of photos in hopes of helping those facing this same issue---it seems a bit common.

Mine works just fine, making this a bit of a PITA. Its leaking between the filler neck and main tank, not sure it can be repaired properly.
Plus I've already purchased a new Ford tank so why not?
Might be willing to send you the old one---it should fit from '92 until at least 2003---PM me!

If you had check valves on your controls, they'd not function because they are 2 way, If you can get at it by pulling the battery and tray, make plenty of pictures, and possibly video of it, I'm needing to get at it one day.

There is another post here detailing cutting an access hole in the right side inner fender to get at the vacuum reservoir: https://www.ford-trucks.com/forums/1...efrosters.html Post #7. Not my first choice but workable none the less.

I personally just installed a new generic check valve in the feed line heading to the reservoir from the manifold. No need to pull that stuff apart. The old valve isnt going to cause any problems unless its stick closed, which seems unlikely.

Drivers side, on the intake manifold, about half way. It crosses the top of the engine compartment heading over to the passengers side. They break all the friggin time. Usually a small red hard plastic line, though in some production years it was black.

help
Anyone got any pics of this apparently I must have found the wrong vacuum line because this didn't work.
