the what is this?? and how do I connect my fuel pressure gauge??
 

Behind the TB is a small part that says BBK on the top of it... if I were to guess I would think it was an adjustable fuel pressure regulator.. I havent owned the car long and the previous owner never mentioned this part..

Also, the car has a fuel pressure gauge from autometer, but I guess it is disconnected because the needle never moves... I noticed the gauge is full of water... does this mean it is bad?? The gauge is located near the windshield on the outside of the car. What is the wireing diagram for the gauge?

I would guess that its just a liquid filled gauge.

Yes, that is your fuel pressure regulator, not necessarily adjustable though.

As 88 pointed out, that could just be a water filled gauge...quite common. Not sure why he would have disconnected it though. Your best bet would be to check the manufacturer website for instructions. I can only imagine that there must be a sending unit somewhere that is disconnected.

yeah its a fuel pressure regulator... it says BBK power-plus on it... half blue on top... has a place where you can turn it on the top

The gauge light lights up, but the gauge must be disconnected... I'll TRY and follow all the wires... or just call the previous owner
