Do the plumbing gurus on this part of the forum also discuss the LPG? I am certain that my 1989 has no pipework to the fridge. Ive never seen this type of fridge (Norcold 663) But im certain that there should be a pipe on the 'nipple' below the electrical solenoid. Theres no pipework that I can see in the rear compartment of the fridge?looking from the outside compartment door.
