Arctic Cat 9000/1100T Boost Recirculation Valve (BOV) Kit

Remove the clamps that hold the existing plastic check valve or cut the lines right at the existing valve. Remove plastic valve.

Install the new brass check valve by first sliding the stepless ear clamps onto the hose, then push the new check valve onto the hose ends where the old plastic check valve was. Make sure the arrow is pointing towards the fuel pressure regulator/manifold hose ends (toward the rear of the sled)

Slide clamps over the hose where the barbs of the check valve are and using a nippers or other suitable tool, squeeze the ear of the clamp so it closes on the hose and becomes tight. You should not be able to pull the hose off the barb or move the clamp when done properly.

For those customers who have the short fuel pressure regulator hose - remove the clamp from the short section of silicone hose that previously went to the fuel pressure regulator. Then remove the hose. Add the longer supplied hose and use the remaining clamp in the same fashion as in step 3.

Re run your BRV hose according to the diagrams below – you will want to make a loop in the line that goes to the fuel pressure regulator – this is to keep the line from kinking. Loop line to the fuel pressure regulator as shown in the picture below

Route the longer free end of the preassembled hose to the EVO BRV – make sure it is routed as in the picture above. Secure hose to BRV with the included green constant tension clamp

Make sure the hose will not rest on the factory heat shields!!!! – if necessary, shorten the hose going to the EVO BRV or loosely zip tie it to the factory elbow. Do not kink the hose

Double check routing and connections

Double check that the BRV cap is on tight (the cap is the part of the valve that the vacuum hose attaches to) periodically check to make sure the cap has not loosened.
