I recently started my engine (O-235 L2C and the oil pressure reading went to 59 psi, w/no fluctuations.
the range for my engine is 60 to 90 psi. I temporarily installed a mechanical oil pressure gauge that immediately registerd 75 psi on startup and fluctuated up to 82 psi as rpm was increased. The elctronic sender is part number 41105. Has there been an issue w/these senders? You have another sender listed as well (silver) any difference between the two? thanks. Don....
