I bought a new oil pressure gauge and it pegs all the way on the high side. The last gauge was black faced and it went to 50PSI. This gauge just has a work zone and is yellow faced. I was told that the yellow faced gauge is only a 0-25 Psi. and the hart parr 70s run 25-30 psi. Is this true? Where can i get the correct black faced gauge???
