Thanks for reply, did you clean yours out and replace/ clean filter it mentioned on label. Assume you can fill it with Diesel oil ? Not really examined it too much yet has one connection with pipe and union for injector and valve on back perhaps this is to release pressure before disconnecting. I did find an American forum someone said had instructions but not for copy yet.
Thanks
Hi Did you get any joy obtaining any instructions for the CAV Injector tester?
I have exactly the same unit pulled out if garage been there for years and have a need to check some injector Pop pressures.
Thanks
