To adjust you must first remove the EHA & since is is in the fuel circuit don't do that with a warm/hot engine. Of course the key must be off. Be prepared to have fuel spray from the connection. Have rags available!

To adjust you will need a 2.5MM allen wrench, remove the brass closing plug (screw) & then the allen adjustment will be apparent.

NEVER move the the adjustment more than 1/6 of a turn at a time. Clockwise will create a higher differential pressure & therefore slightly richer at WOT.
