Fuel pick-up fitting: See Figure 7.41.

The fitting consists of a brass 90 degree elbow
and an plastic tube.

The tube reaches to near the bottom of the fuel
tank and is shrunk onto the fitting.

When diagnosing a fuel starvation issue do not
over-look the possibility of an air leak between
the elbow and the pick-up tube.

that escapes. It also allows air to enter the fuel
tank to take up room in the tank as the fuel is
used.

The fitting consists of a plastic chamber that
contains a regulating orifice.
