Expert:  Eric replied 8 years ago.
I am sorry, I will have to opt out as I dont have a diagram for non-catalyst system. If another expert has a diagram they will be with you shortly
Expert:  Eric replied 8 years ago.

Hi,

 

Another expert who has been with Ford since 1974 let me know that since 1976 all vehicle made in US or for US have a catalyst system. IF yours is missing, then it was removed and therefore no longer a factory system.

do you need more information?
Expert:  Eric replied 8 years ago.

Hi,

 

Is your vehicle in the US?

Customer: replied 8 years ago.
yes
Expert:  Eric replied 8 years ago.

Hi,

 

If yours is US made, then the diagram I supplied is the correct diagram for a 1978 Ford F250 with 460 engine. From the factory it came with a converter and Egr system. If they are not on the vehicle, then they have been removed. There are no vacuum diagrams available for altered or tampered with systems.
