Hi all, as the title suggests I am trying to remove the push in air line fittings before removing the air tank as everyone knows you just push in the collar and pull on the pipe unfortunetley they just will not move I have tried squirting with WD40 leaving overnight then blowing any dust and grimme that may be jamming the collar with the airline with no avail. I only want to cut into the lines and put a joint in as a last resort, does any one have any ideas on what else to try?
Tapping round the connectors with a hammer sometimes helps.
Par for the course. The pipe has probably been pushed in too far. Cut the pipe and renew the fitting.
