mine is a little above the red circle.. it is the 4hp 10 gallon model.. I was at Lowes or Home Depot the other day and saw a Campbell Hausfeild compressor with the same pump. the preassure switch was the same too, with the pull up for on rather than the lever that most portable compressors have...
on the other hand, today just b4 I came in I noticed the cylinder head leaking out of the front bottom seal.. I'm going to call and see what they have to say.. more than likely they will send me a new head gasket set
