The best answer I can give you is to pull an injector from each and compare them. If everything looks good, hook up the 90 injector to your 96 harness WITHOUT inserting it into the manifold and see if it works. If so, then I'd say yes.

It might help if you have a pair of calipers to check measurements.

It most likely will work. What engine is in each. If both are 302-351 or both are 300 etc then it should. I have Ford Racing injectors for a 87-93 Mustang 5.0 in my truck. As long as they are the same color they should work. There is a possibility that the connector is different, but I don't think it is. I wouldn't think the injectors in a truck thats that many years older would be better than the ones in the 96 though.

As long as they are the same color(= same capacity) they will plug in and work fine.

Difference in the cone shape on the spray end.
The 90 has long conical cones and the 96 has a rounded end.
There is a difference in length of 1/8"
Does anyone see a problem.
PS. the reason for the swap is the injectors in 96 have 250 thousand miles and the injectors in the 90 have less than 20 thousand

I doubt you'd have to worry about it- as long as the replacement injector seals properly into the manifold and is compatible with your current system, you should be okay.

Just out of curiosity, which one is longer?

the longer one is the 90, an the difference in length comes from the nozzle end, the length from seal to seal is the same the nozzle on the 90 ingectors are cones and 1/8in longer than the round and flat nozzle on the 96

The newer injectors probably have an updated (better) spray pattern than the older ones, but as long as the flow rates are the same, it shouldn't cause any major problems.

The overal length doesn't matter either, I have a set of Design 3 injectors here and they fit these trucks no problem as long as you use at least 4 of the same on each side of the engine.. and preferrably a complete set of 8.
