I was pulling apart a set of nitrous works solenoids to inspect them before I install them on the car, and I made the mistake of pulling both coils off at once. Now I don't know which base/tower/plunger go with which coil.


The differences I note in the tower/plunger/base are:

Black vs White oring
Small vs Large plunger seal
One base has a larger orifice. The smaller orifice looks like there is an "insert" in it or something...


Any help would be great.

My guess is that fuel is on the left.. any suggestions?

am I correct in saying that with same series solenoids, the fuel one always has a larger orifice? (most common .125 -> .063 for small series)


So, I could safely say that the obviously larger orifice is the fuel one... right?

Usually yes. The larger of the 2 bases should be fuel. The top part on the right is the fuel. easiest way to tell is to look at where the plunger has been seating on the orifice. The bigger of the 2 seating rings is from the fuel.
