I have an Hitachi EC12 compressor & I am having an issue with a blow out of pressure before it reaches completion of its cycle! I thought it was the blow back valve & replaced, but now found that it is leaking from the relief valve that connects to the back of the pressure switch and then has a hose that runs to the non return valve.
Thank you for your time

Hi @west40texas
The hose is part ID #52 Hitachi part # 881-675 (supplier example only to show part) as seen in the parts list for the compressor, which shows that it goes to "A", but there's no other indication where "A" connects to.
I think it may be part ID #64 Hitachi part # 881-493 (supplier example only to show part)
If you think that it may be the one, search online for Hitachi 881-493 to find suppliers that suit you best.
