Fuel Line Coupler: Description and Operation

Figure 2 Legris Connectors:

In order to perform speedy remove and refit operations, the underfloor steel lines are linked through the engine bay bulkhead to the flexible tubing, leading to the fuel rail and the fuel regulator by using positive sealing, quick-fit "Legris" type connectors. At connections between hoses and the underfloor pipes, the pipes have a ridge or paint line to indicate how far the connector should be pushed onto the pipe end. The same type connectors, are used to connect the fuel feed and return line to the fuel tank.

CAUTION: Pipes and component stubs must be fully inserted into connector ends to ensure proper fit; failure to do so could cause fuel leakage.

Connectors used inside the engine bay are of different sizes to correspond with the difference in pipe diameter. There are two sizes of connector, 8 mm and 10 mm, this is to ensure that the feed pipe is not connected as the return pipe and vice versa. The 10 mm connector is used for the feed line. The connectors for the feed and return lines at the fuel tank are the same size.

Except for the return line connector at the fuel tank, two release tools, one for each size of connector are required to release all remaining connectors.





The connectors are released by pushing the tool into the female half of the connector and at the same time disengaging the latches.
