Hello,
is this why my 50 lb oil pressure gauge pegs instantly all the way over off the map to the right and stays there while running ? I had a 1940 239 8cyl flathead motor rebuilt and just realized looking at receipts my machinist put an 80 lb pressure oil pump in it . There is a 50 lb oil sending unit on my truck . Is this the problem ? It is a stock 1940 oil gauge on a 12 volt system with the voltage reducer . Is changing out the oil pump a lot of labor ? Is there an 80 lb pressure gauge to replace my 50 lb that will fit the cluster ? Will an 80 lb sending unit make the 50 lb gauge read normally ? All help is greatly needed .
Best Regards
