8.2 Fuel Standpipe Installation

This separate fuel pickup precludes any effect of

pressure.

Where available, a spare NPT threaded port can be

utilized for the standpipe. If a spare port is not present,

proceed with the following instructions under “To install

the standpipe”.

Figure 17: Webasto fuel standpipe

To install the standpipe:

1. bore a 25mm (1”) hole through top of fuel tank

(item G, Figure 17).

2. remove sharp burrs and smooth edges with emery

cloth.

3. determine length of standpipe when installed. End

should sit at least 25mm (1”) above tank bottom.

Cut off excess standpipe at a 45 degree angle.

Remove burrs.

4. loosely assemble items C, D, E, and F (Figure 17).

5. place sealing compound on threads of item B and

thread into item F. Tighten item B completely.

6. slide standpipe into hole at angle. Slip one shoulder

of item F, Figure 17 inside the hole as shown in

Figure 18.
