Fuel Supply Hoses - Installation
Fuel Filter to Fuel Injector Hose
1. Starting on the starter motor side of the engine, feed the
fuel line underneath the fuel pump mounting bracket and
over the top of the blower housing.
2. Continue to feed the fuel line underneath the cylinder
head air guide until the end of the fuel hose reaches the
fuel injector.

supply hose. Slide clamp each down the hose away from
the hose ends.
4. Press the fuel supply hose onto the fuel injector supply
port until the end of the hose meets the port flange ( A ,

1. Install the fuel hose clamps onto the ends of the fuel
hose. Slide the clamps along the hose and away from the
ends.
2. Press the fuel hose onto the fuel pump port until the end
of the hose meets the pump port flange ( A , Figure 31).
3. Feed the fuel hose underneath the fuel pump mounting
bracket toward the center of the engine.
4. Press the fuel hose onto the fuel tank port until the end of
the hose meets the tank port flange.
5. Squeeze the tangs of the fuel hose clamp and slide
clamp along hose until positioned above the fuel
pump port, approximately 1/8 inch (3 mm) from end of
hose. Repeat this procedure for the fuel tank side of the
hose.
If fuel return and vent hose service is required, proceed to
the appropriate instructions. If fuel hose service is complete,
