Oil Pressure Sending Unit

[keelhauled]

Simple question... how does one match an oil pressure sender to the gauge? Mine started to leak, so I replaced it with what was supposedly the right one (according to NAPA). Now I read 60 psi with the engine off and 85 at idle. It's off the scale at speed. It's ok for now, since I know I have pressure but I'd sure like to have the right one.<br /><br />Oh, and yes, the gauge worked fine with the old sender. It's a 305GM w/an OMC Stringer. Not sure of the gauge manufacturer.<br /><br />Thanks!

are all oil pressure senders universal for all mercruiser engines, because the one that its telling me to use does not look like the one i took off my engine, its a 1994 can these new ones just be different
