PM pressure switch..

[GNMatt87]

Hey guys,

Does anyone know what size wrench/socket is needed to remove the pressure switch? It has to be torqued down from what I understand, right?

Thanks,

i have the same question, just put on a rebuilt unit from kirban, all is well, but i noticed very slight seepage from base of switch, want to check o-ring. i think i read torque of about 20lb somewhere.

My old,sitting for years but brand new switch was leaking at the base or the round flat surface of the MC below the switch. I pulled the new switch which was from a Cardone rebuild and there are two o-rings; under the top narrow o-ring which sits in a narrow groove there is a very small vent hole and that might be the source of the fluid leak.
