DIY WUR Installation ?

[ikarcuaso]

Is this something a relative noob can handle? If so, can someone point me toward some related threads and/or links (sorry, maybe I'm not searching the right keywords or whatever). Or should I just pay the man?

If it's straight-forward enough, and another Bay Area pelican is willing to hold my hand for beer and/or food, that would work, as well.

TIA for any input.

Easy.

Make sure motor is cold. Have a fire extinguisher at hand. Get a rag to catch the fuel dribble. Carefully dissconnect the wiring plug to it. Disconnecct the vacuum hoses to it, top and side. Get the rag and put it underneath the WUR to absorb fuel. Take your 14mm wrench and disconnect the WUR to fuel distributor line and drain it into the rag. Move it out of the way without kinking it. Disconnect the other fuel line banjo fitting (mine's a 78 with nylon lines). Carefully remove it with the 2 copper washers and nut (locally difficult to find parts). Put them in a safe clean place. Get a 5mm hex socket and remove the bolts that hold it to the intake runner. Remove the fuel fitting from the old WUR and put it on the new one. Install the new one. Check for leaks. Before cranking, lift the sensor plate up to fill the return line with fuel (don't overdo it). Check for leaks again before starting the car!

Hope it helps.

The only thing I would add to the above description is to be careful when trying to break loose the mounting bolts for the WUR. Mine were pretty rusted, and I ended up breaking one of them. Then I had to spend an hour getting the remaining piece out, using vice grips in an area that doesn't really have room for vice grips.

So it may not be a bad idea to spray the bolts with PB Blaster or similar a few times before you start. Try to get some into the area where the bolt threads into the flange at the bottom of the intake runner, if possible.

Good luck
Scott

What makes you think your WUR needs to be replaced?

Because I have a replacement WUR sitting here. And replacing the AAR didn't seem to help my cold start problem. And I'm completely caught up in this ghost-chase.

Oh yeah, and my control pressure when cold appears low, ~10 psi or so. Unless it was measured wrong.

Gotta love CIS.

Vash, I appreciate the offer. I'm gonna stare at my engine a bit more, and then I'll PM you.

Vash knows CIS better than most. You should take him up on his offer, and I'll come by to lend more support and drive you both crazy by going on-and-on about the wonders of carbs. I will add this to your ghost-chase hit list: never underestimate the annoyance factor of the decel valve. Before you do anything else, you should plug the vacuum line to make sure that it isn't the source of your woes.

Yup, I plugged the decel valve's vacuum line.
