FUEL SYSTEM INSTALLATION

8.1.0 

Make sure that you select a good location (usually in the bilge area) for the lift pump    

   

(037236) with good access to change the filter and water drain as shown in Figure 8.2a.

8.2.0 

Make sure that you install the lift pump within ±11° of vertical (it must be installed    

   

vertically in the range of angles given).

     

Figure 8.2a. Lift pump in vertical position

8.2.1 

Ensure the total length of vertical/horizontal pipework lies within the green area of the  

   

plot below.  

     

Figure 8.2b. Tank fuel pickup distance

   

  NOTE

The guide for tank fuel pickup distance from the outboard rigging grommet (that is the relationship 

between the vertical and the horizontal distance between the outboard and fuel tank), is given in 

the chart in Figure 8.2b and Figure 8.2c.
