Hey there,
Got a 1980 240DL with a B21A.
I have a buddy who might sell me a Ractive Oil pressure guage for cheap.
I just have a few questions about installation.
1. What thread size is the stock oil pressure sending unit?
2. IF the Ractive sending unit DOES fit in the stock hole, what do i do with the original black wire leading to the wiring harness and OIL light in the dash?
3. IF the Ractive sending unit DOESN'T fit, is there an adaptor i can buy to make it fit?
Anyone out there who has installed a pressure guage with any tips?
Thanks in advance
