I have replaced all my gauges and my oil pressure gauge seems to be metric. I think it is a m10x1.0. Not positive but I think the incoming oil line looks to be about 7/16x20 NF. At Least a 7/16 fine thread bolt will screw on the gauge but it's deteriorated. Is that the correct size? Do they make a female adapter for this problem? Surely others have ran across this before. Or will I have to replace the line from the block up? If so what size is the block fitting? Thanks
