Quote from: Feather535 on Yesterday at 05:15 PMUhoh, now you're down the rabbit hole! You will absolutely need to remove the WUR. The filter is indeed inside one of the fuel line fittings, the larger of the 2 if I recall. It's very fine mesh. To clean it you'll need to take the damn thing apart and blow it out with carb cleaner. This is described here someplace, best to do a search. When you open the WUR you'll see 4 flat-head screws that need to be removed. Be careful, they are VERY tight and hence easy to strip. Put the WUR in a vise to do loosen them. And handle the thin steel membranes with the utmost caution.

Where is that filter? I disconnected the hard lines from the WUR and removed the adaptors they connect to, but there is no filter there. If it's inside the WUR, I'll probably need to remove it from the car to access it.

Quote from: Feather535 on Yesterday at 12:10 PMNow I'm looking at the WUR and all the related plumbing on this 280SE. It's hard to see under the intake manifold and even harder to access--but there appears to be another pressure regulator in the return line downstream of the WUR before it goes back to the fuel distributor. The factor CIS manual calls it a pressure damper. What does this thing do? Do they ever go bad? It looks similar to the pressure regulators in Bosch pulsed injections systems, which have been known to fail.
