I have a 91 F150 4.9, I recently replaced the engine and pulled of the air pump lines so the only thing that remains is the pump. I would like to remove the pump with either:

smog pump eliminator
Search Results for smog - SummitRacing.com

or

Shorter Belt

-----------------

Does anyone know what size belt I would need and how to route it, I dont have A/C or does anyone know if one of the 5.0 smog eliminators will work with the 4.9? I did search already and did not find my answer.

 

I think the last guy who measured one out came up with 79.5 inches.
