New 1000 Serie » New fuel lift pump

A new fuel lift pump (A), has been introduced for use on four cylinder New 1000 Series. The new pump is a one-piece assembly and should not be dismantled. A strainer (B1) is fitted inside the fuel inlet connection (B3). This strainer is cleaned at the same service interval as the strainer fitted to other fuel lift pumps. The procedure to remove and to fit this fuel lift pump is as the earlier fuel lift pumps.

A kit, is available that provides a fuel lift pump and a joint.

3. Release the hexagonal fuel inlet connection (B3).
4. Remove the strainer (B1) together with the ‘O’ ring (B2) from the fuel inlet connection.
5. Clean the strainer in clean diesel fuel and dry it with low pressure compressed air. A kit, is available, which provides a strainer and an ‘O’ ring.
6. Fit the strainer into the fuel inlet connection and fit a new ‘O’ ring, if necessary.
7. Fit and tighten the fuel inlet connection to 20 Nm (15 lbf ft) 2,0 kgf m.
