Hey everyone I have a Oil Pressure Gauge I received from Mr. Bill Cody for my new GAST pump when I put it in. It would appear its getting a bit low on oil in the face of the gauge. I was wondering if I can add a certain type of oil to this gauge with the small hole on the top of the gauge? When I first got the gauge it was about 3/4 or so full. It had a small air bubble at the top which Bill said was fine it needs to be that way. But my small air bubble is almost half of the gauge now... So if I can put oil in it through that small hole my next question would be of course what type of oil?

Thanks,
RC

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
