Question Prosport Oil Pressure Gauge Install - Problem ?

Okay, so I bought a Prosport oil pressure gauge, and volt gauge off of I got my volt gauge hooked up no problem. When it comes to my oil pressure gauge, I'm not having luck. I did all the wiring like everybody has said on forums. I bought the m12x1.75 adapter and tapped into the block. Black wire is ground, green wire goes to the oil sender, and the pinkish wire and red wire go to a 12V source. From the sender, one nipple goes to ground, and the other goes to the green wire. I did all of that. As soon as power is put to the gauge, the needle maxes out and just sits there. I thought I may of hooked something up wrong, so I disconnect the wires going to the oil sender and switched them around...still no luck. So then I disconnect the green wire that runs to the gauge, the needle still maxes out and just sits there.

I have no idea what's wrong ? Yes my ground is good because I am using the same ground for my volt gauge and my oil pressure gauge. And yes the gauge lights up like its supposed to when power is put to it.

I'm lost, please help !!

Could be a faulty pressure sending unit from the maker. if the wiring is right, then you should be looking at the mechanical portion of it (the sending unit). I'd ask for a different one under warranty. If the new one still doesn't work, my may want to look into a new gauge. I'm betting it's the sending unit tho.
