Im a v8 guy, havent worked on a 6. The end on the block has the sensor, if you pick up a mechanical gauge, the fitting will likely screw into where the electric sensor screws in. I use copper but would use copper/steel now, but the vinyl line will work fine for checking the mechanical oil pressure, just replace it if you choose to keep it in place. You may have an oil pressure problem if increasing rpm doesnt change anything.
Put some marvel mystery oil in it and drive it, may help, may not, but wont hurt. If the car hasnt been driven a lot, it could be something the marvel can cure/help.
Rereading through this thread and missed the mystery oil suggestion. Which one do you recommend? Does this go in with the regular oil or into the gast tank? Thanks, Jeff
This stuff has been recommended for use in your oil, do you have an oil filter ? Not sure when they were available on a 6. Id follow the directions on the product. Ive never used it , but am a frequent user of Sea Foam in the gas tank, great for cleaning varnish gunk out of the fuel system and valves, if you drive at highway speeds a lot, no issue with gunk/varnish. It also can be used in the oil like Marvel Mystery but Ive never used it there.
Best to use premium fuel too and ethanol free if you can find it.

That's great, thanks so much for taking the time to find the links. Any idea why they call it the 7000 series?
Collectively each division had it's own number to refer to a range of cars.
Chevrolet had 1500 & 1600-series (1500 are Biscayne / Bel Air, 1600 are Impala / SS / Caprice).
U.S. Pontiacs were 2000 series, Oldsmobiles were 3000 series, Buick 4000.
The Canadian Pontiacs were 7000 series, but to expand on that the leading 7 was used instead of, say a 1, so a 154-series Chevrolet Biscayne would be a 754-series equivalent Canadian Pontiac Strato Chief.
Canadian GMC trucks used 9000 as their series designation, modifying the Chevrolet truck model #s. A Chevrolet series 10 pickup would be a 910 series Canadian GMC (U.S. equivalent is a 1500....) Generally...
