Hey everybody...I'm sure this has been covered though I couldn't find a thread on it...easy question though. I'd like to install an oil pressure gauge in my max and just wanted to know which to use, mechanical or electrical. I'd prefer electrical since it's easier to run a wire into the interior vs. a line, but I need to know whether an electrical would even work based on how our sending unit operates. Does it operate as an on/off switch? If so then the electrical wouldn't work and I'd need to go mechanical. Let me know, thanks

 

the electrical gauge has its own sending unit. it has nothing to do with the stock switch. you can either use a tee so the new gauge is connected and the factory switch/light will still work, or you can use just the new sending unit. the stock light is useless any way. just remember the nissan threads are bspt and the aftermarket gauges are npt. you need to get the correct adapters or a leak could develop.

 

Thanks a lot...all I needed to know. I'll prob wind up just using the new sending unit and forgetting about the stock light. Because I agree with you...it's pretty much useless. Thanks again

 

i have my idiot light turned off, and i just run the aftermarket sender. You do have to buy a BSPT adapter, which can get pricey, I payed 19 bucks shipped for it. It's a little piece of metal.

 

is it like this one?

It's a nismo one, but seems to be cheaper than the one you bought. Will this one work on our cars?
thanks

 

check that price with shipping.

 

nissport has adapters too, even more money, but much better quality and more fittings for turbo use too.

 

umm i bougth my npt to bspt adapter from autozone for 5 bucks..oh and "t" fitting so that i can have the stock light, and the autometer oil pressure gauge..

 

$5 for a peice of brass which will break when using a heavy electric sending unit. I wouldnt chance it. unless you run the tee up somewhere else and its not supported by the oil fitting.

 

I do concur.

 

To my knowledge it never broke, or leaked.. I had it for about 100k miles..

 

Holy friggin crap!!! I just checked the shipping to Canada... 55 us? What a rip for a $10 part.

 

was it an electric gauge? chances are it wont fail, but you never know.

 

yes sir.. the autometer oil pressure sending unit is big, but not enough to cause problems.
