FD is 550 primary and 850 secondary side feed. Not top feed

 

You can test them by putting stock fuel pressure to the injector, then get a beaker or other fluid measuring device and apply 12v power and ground to the injector so it will open. Then you will need to time 1 min while spraying the fuel in to the beaker and see how manny cc's of fuel were flowed...



I have 3x 20B 550cc injectors here that I beleve are the same as the FC injectors, but the FC actually used 2 types of 550 top feed injectors. One has a squared off connector on it and the other has a more rounded off connector. The ones I have are rounded off type that came on the newer models of the FC.

 

I have a Greddy Rebic IV (brand new) if you are interested. I don't know what you plan on doing, but am just letting you know that I have one up for sale. $490shipped.

 

I have an extra gas tank in nice shape...I didn't know there was any demand for these, but shipping would be from Kansas City.
