Anyone know what size is the fitting on the oil pressure gage for the 3/16 copper tubing on 1950 year model?
I tried using the 1/8 line kit from auto zone but my gage shows no oil pressure. I have plenty oil going to the rockers and when I forgot and left the line on side of block off and turned the pump with my drill it pumped out two quarts of oil before I saw it.
So either the line has to be 3/16 or I have a bad gage.
