REMOVAL AND INSTALLATION OF FUEL PIPES

1.

Cut off the pipe behind the nipple or banjo
union. Remove the section of pipe from the
nipple or banjo union, by heating. Never
remove the nipple or banjo union by making
an incision in the longitudinal direction of
the pipe. This could easily result in damage
to the hose adapter. Even minor damage to
the hose adapter will cause leakage.

2.

It is not permitted to fit a nipple or banjo
union to the same pipe end more than once.
If a nipple or banjo union were fitted to the
same pipe end more than once, this could
result in bad sealing.

3.

Cut off the pipe end if it has been used
before. If shortening the pipe results in a
sharp curve in the pipe or if it makes the
pipe too short, the pipe will have to be
extended or a new pipe will have to be
fitted.

4.

Always install nipples and banjo unions in
plastic pipes with the special tool
(DAF no. 0694829).

5.

Clamp the plastic pipe in the special tool.

6.

Note:
Never heat a plastic pipe when fitting
nipples or banjo unions.

Use a plastic mallet to tap the nipple or
banjo union into the pipe.
