Post subject:  mechanical oil pressure gauge.

Since my oil pressure warning light came on and the pressure bypass section of the oil pump looks good, I was going to install a pressure gauge to find out what the true pressure is.

I see that most have a 3/8" fitting but it looks as if the pressure sending unit has a large 5/8", fine thread fitting. Should I find adapters or is there a pressure gauge that will fit?
Does anyone sell replacement oil pressure sending units for the warning light?

Any auto parts store should have the sending unit. As far as the mechanical gauge goes, some kits have a couple diffrent addapter and if yours does not then a good hardware store with brass fittings will do the trick.

But before you change the sending unit check and make sure the wire is in good shape. I found mine became brittle from the heat and was grounding out making my light come on.
