    :confused: Does anyone out there have some knowledge on the air injection pump setup and hose routing this truck uses? Any reference material you could provide would be helpful.

    Pump assembly had been removed from engine (seized & trashed) several years ago & never replaced. Truck runs fine, but now requires all emissions control components to be installed in order to pass the dmv inspection. In a bit of a tiff since I have no reference on what goes where or what parts of the assembly are missing.

    It would be helpful to know what engine/trans combo you have.
