Default Oil pressure sending unit part number

Anyone able to look up what the part number for 70 GTO oil pressure sending unit-with rally gauges? My current one works fine just does not "look" correct. As I recall the unit should be black in color? Mine is the common "gold". Looking to buy one and I am guessing this won't be cheap! Thanks, Jimmy

I don't have my MPC here to check the original part number but I see them on eBay from time to time, I think $500 is the going rate and being in a box for 49 years I'd have my doubts about the diaphragm being sound. Maybe a bit of black rattle can ;-)

6462137 is the correct part number. For 70-71 they were black but the ones I have seen on 72+ Olds were just the gold cad zinc/cad plating. I have seen other gm numbers that look identical, are 80 lb units, and have the 1/8 NPT fitting that go on Ebay as well. These get priced up too but not as bad. I have a few of these off-numbered ones i have picked up over the years.

Correct, but just to be clear, the originals were black and the bottoms were gold cad (where the pipe nipple is) The black top part is crimped around the bottom cad part.

GM still makes this sender brand new, identical shape, but different part number and of course date code. IIRC, its a duramax diesel oil pressure sender, I think it wrote it down somewhere, see if I can find the new number. It took me a few years to find a nice working one with the right date code. For the time being, paint the cad one and keep your eye out.
