Oil pressure gauge sending units have such a varied price range. Is this a true example of ‘get what you pay for’. Or is manufacturer more important for accurate readout? NOS could be fine but not critical. Thanks! 

Thanks. Kinda what I was hoping againstAnymore you just don’t know.
I'd go with Standard brand for aftermarket.
I'm not sure I'd trust a Standard brand oil pressure sender after my experience with their craptastic water temp sensors...
Thanks. Found PS59T. The other brand I found is Wells but cost is about 4x. That’s why I wondered if you get what you pay for with these switches.part number will end with the letter "T".
In that case, I’d go with Wells. And cross fingers, you just never know.Thanks. Found PS59T. The other brand I found is Wells but cost is about 4x. That’s why I wondered if you get what you pay for with these switches.
