hi buddy
you're best off finding exactly where the leak is coming from, then i'm sure someone will be able to diagnose your problem and then tell you what needs to be done and if any parts need ordering/finding
the easiest way to find the leak will be to:
-disconnect all connectors to the board from the solenoid and eyes
-take the frame off
-re atatch the macroline hose and regulator (with the frame detatched)
-air up your gun, you won't be able to shoot it but it should be easier to find the leak
however i doubt it will be the solenoid as the ego5s have one of the most reliable solenoids in the business
is the gun having any other problems?
has it been regularly maintained (stripped and lubed)?
does it still shoot?
hope this helps
