Did you use a 1/4 inch universal and 10mm deep well socket? I think that would work, or the other alternative is to take the oil pressure sender out. How big of a deal is it to take the oil pressure sender out? I am putting my Greddy sensor in the stock location and relocating the stock to the thermostat housing. Anyway, thanks.

 

Is yours that tight I just got mine out with a 10mm open end combination wrench?

 

I don't know, but it looks like it is set in too far to get a open ended wrench on it. Maybe I am looking at the wrong sensor. It is to the left and below the oil filter. Looks like a 1/8 NPT fitting with one wire connection on it. Is that the right one? I am trying to get it out today, so I will try the open ended wrench.
