what is the stock fuel injector size for the 4.0 ohv engine.?
 
IIRC 19lb/hr is stock, 24lb/hr is the usual upgrade for a forced induction setup.
 
Do they color code them like other ford motors? I ask because I have two 4.0L motors with two different colored injectors. Not to high jack but figured this might fit in this question size.

There are three different colors, but it's far more important to have the correct injector for your computer than for any perceived need to upgrade.

There is the right ammount of fuel and ANY OTHER AMMOUNT is the WRONG ammount.

The early 1990-92 Engines came with grey injectors
The 1993-? came with red injectors

Aftermarket replacements and some batches of stock injectors for
either came in black. (and at that point you are only guessing)
