Here is a photo of the one I have. This number may (most likely) have been superseded by another number which isn't uncommon but should help with your search.

The p/n in Mike's photo is the most recent one we have on the forum, although it was last referenced about 10 years ago.

Found a more recent mention from AdventureSofie  Hyd air solenoid issue 29557354

ETA, the price has definitely gone up, but I do see this open-box one on eBay for $300, and there are a couple of others in that price range before it jumps to double.

The retarder valve is related to the transmission, not the engine.

Thanks Pamela and Mike  It's good to learn this valve will work for both the 320 and 295  Most people responding seem to have the 320  I called Foretravel yesterday they had no aftermarket numbers Then I called Keith he was checking on optional valves also So thanks for that part number you gave me I have it ordered        Leonard  and Sherry            When I cleaned and oiled the valve parts  I tried to look for a tear in the diaphragm    it may be too small to see  8035306652

It's just a solenoid air valve. You could probably use other stuff, as long as it meets the voltage/current draw specs.

When I bought my RV forever ago, the retarder air valve was not working. It was stuck and did not put air into the accumulator during retarder operation. However, the retarder still worked, it just took several seconds to activate and start slowing the RV down.

I found a new-old-stock valve on ebay for like $30.
