It is a Nikki unit and i am looking at two different things. One has fuel lines and coolant lines going to and from it, the other is about the size of a fist and has only fuel lines. The first one is flat and about the diameter of a soft ball while the second looks like a solenoid. Both are nikki. The larger unit has the larger hoses and "pressure test, Fuel plug" written on it while the smaller one has 1/4" metal lines.
