Fuel System; Trouble Shooting Guide - Husqvarna PT26D Workshop Manual

Fuel system

Trouble shooting of the fuel system is described in the Perkins Manual \ SOTA \ Fuel System Inspect and
Air in Fuel – Test.
The suction line between the tank and the feed pump is the only fault source on the Husqvarna side of the
interface, that can be the subject of trouble shooting actions. Check especially that partial air cannot leak in.
• Check that the connections are tightened.
• Check that the hose does not have wear or crush damage.
• Check that the connection in the fuel tank is undamaged (even on the inside).

Trouble Shooting Guide

We hope the following trouble shooting chart can help you during trouble shooting. It is not fully compre-
hensive, but deals with most theoretical fault causes. As space in the chart is limited, there are supplemen-
tary trouble shooting instructions in this chapter.
The trouble shooting chart starts from fault functions without mutual order, you can therefore start trouble
shooting in any fault function.
By following the lines from the fault function you are led to a number of possible fault causes and proposals
for corrective actions.
