In order to use 18.4/16.1s on the front of a 7000 series how many holes must the front axle be extended outward to ensure there is no interference with the frame rails when in a full turn or when the axle oscillates in a turn? I'd also like to know if that is different when the tire size is dropped to 16.5/16.1. There is an option shown to have a secondary factory spin on fuel filter c/w an electric fuel lift pump mounted external to the right hand frame rail approximately below the glass fuel filter. Would anyone have a photo of their tractor with that set up as a factory option. Just curious how the fuel lines were routed. Based on the mounting location it must also impact turning interference considerations. Any help is appreciated.

I remember 7080's having those tires and the axle was completely narrow.

All of that extra fuel system junk on the later tractors was mounted on the inside of the frame rail.
