F150 without compuvalve

[Highmarker]

Which years of the F150 had the compuvalve installed and which years do not? I have heard that '97 - '02 have the compuvalve, and that '03 - '04 do not. Is that right? If '03 - '04 do not have the compuvalve, then what do they have in its place?

I'll dig out my TSO DVD and see if I can get some screen shots of it.

Here is what Ford says about the operation of the ALT injectors:

The injector sleeves are placed in the injector seats. The gasoline fuel injectors are placed in the injector sleeve seats. When the gasoline fuel injectors are de-energized and the CNG injectors are energized, the sleeves bypass the gasoline fuel injectors, delivering alternative fuel into the intake system and providing a path of fuel flow from the gasoline injectors.
