SYMPTOM/CONDITION

Fuel flow restriction at medium to wide open throttle type operation on subject model vehicles may be due to a kinked fuel supply hose restricting the fuel flow. Prior to replacing components (fuel pump, etc.) to correct an insufficient fuel flow condition, the fuel pump-tofuel reservoir hose should be replaced as follows to insure unrestricted fuel flow.

PARTS REQUIRED

1 - 1/4" Fuel Hose (pre-cut to 16-1/2" long) PN 4279992

FIGURE 1:




REPAIR PROCEDURE

1. Remove the original hose and sleeve assembly between the fuel pump outlet nipple and the fuel reservoir inlet nipple. Save the hose clamps (Figure 1).

2. Slightly loosen the thermostat housing bolt that holds the reservoir and rotate the fuel reservoir clockwise against the stop furthest from the carburetor and hold it in that position and retorque the bolt.

3. Replace the pump-to-reservoir hose with a 7" piece of 1/4" Fuel Hose PN 4279992 supplied in 16-1/2" length.. Cut to 7", two repairs can be made from each 16-1/2" length. (Do not reinstall the original sleeve over this hose.) (Figure 1)
4. Reuse the spring-type clamps from the original hose.

5. Check the hose routing to make sure that:

a. The new hose is not in contact with anything that may cause chaffing. Reposition as necessary.
b. The new hose has a generous radius that is not going to kink. Reposition as necessary.

6. Start engine and check for fuel leakage.


POLICY: Reimbursable within the provisions of the warranty.
