On my 75 (2028) the underhood appears stock, still has 2bbl, factory
breather, etc. the top heater hose (larger) goes from the water pump to the
heater core. It has a T fitting in it that has a 3/8 hose that runs around
on the intake to a fitting with a vacuum switch on the left rear corner.
the lower hose has the control valve on it ( close to the fire wall) then
runs to the front right of the intake. Both hoses just flop over the rocker
cover and do not attach any where. There is a wire harness that does clamp
to the inner fender in a place that one might expect to find the hoses
clamped to
