Where is the retarder accumulator valve?  I looked for it yesterday but didn't find it.

It is located on the end of the accumulator tank.  The tank should be on the passengers side of the coach just to the left side of the rear most  basement door.  On most coaches your age this is hid behind or to the rear of the batteries.  The tank will have a short 1 & 1/4"  hose connected to one end of it (this will be almost "U" shaped)and there won't be a matching hose on the other end as this tank is kind of like your expansion tank for the domestic water system.  This has oil on one side of the piston and air on the other side.  I can't post a picture right now of what you are looking for though or I would.

Hope this is some help

My 3060R is always sluggish on take-off;  as soon as it finally makes the gear change the 'pep' is suddenly and refreshingly obvious.  I have just considered that's the way it's intended to operate, but it is a frustration.  Maybe I need to look into it further.  Thanks for the postings.

Not right. Mine is off the line quickly, often before automobile traffic in adjacent lanes, even towing a fairly heavy trailer.  Doing the muffler delete and adding a resonator and 5" exhaust perked it up a lot.  Before this mod it was slower to spool the turbo up but never as you describe.

I would suggest you Talk to Brett Wolfe about the failure of the HUIE pump, or google HUIE pump failures.
