hello, i replaced my sender unit with an ebay one, at it showed at first 15psi at idle, then after some months it showed arround 5psi at idle, so i changed it again but this time with the OEM one from nissan, now it shows 30psi at idle..Could it be that how tight i adjust them causes fluctuations on readings? could i have bolted this one too much?

 

I doubt it


You just got the right one now

 

And be very careful of overtightening that sender, because you will crack the upper sump. Why don't people learn to just by the right part the first time?

 

I was told it was oem without packaging, that's why I bought the eBay one.
