Well I couldn't find the red injectors but it looks like they would need an adapter for the electrical connection anyway. The red ones flow more than the stockers so they may not work in our Lima motors. Could be a great swap for the MZR/Duratec motors in the later rangers though.

I did find some gray injectors from I think a 2000 Contour with the 4 cyl Zetek. They are a 4 hole injector that pretty much match the flow rate 14# I think of the stockers. The electrical connection is the same.

So I got them home, removed the seals and little filter screen. Only a little crud came out. To clean the injectors I put a clear vinyl tube on the spray side and secured with a small hose clamp. Filled the tube with seafoam and clamped a shrader valve cut from an old bicycle innertube on the other end. Pressurized it to ~40lbs and applied 12 volts. A little more crud came out. Then I attached the tube to the supply side of the injector and repeated. The spray pattern was not good. I don't know if the test was poor or they are shot. Too cheap to pay $100 to have them professionally cleaned and checked.

I don't drive the truck much anymore and it looks like I'll be selling it to move anyway so I haven't been motivated to chase down new screens, seals and gaskets for the swap. You may try the Zetek injectors, it may be better than the orange mustang injectors as the flow rates match more closely. Impedance, dimensions and connectors should be the same also, you get the benefit of the 4 hole atomization.

As our heads have only one intake valve and the 4 hole injector spray patterns usually are for two intake valve heads, I don't know if there will be much gain due to fuel being aimed directly to the intake port walls. Then again it may still be an improvement over the old ones.
