HL 90
6.1. Fuel supply with fuel extractor
In vehicles with large engines (trucks), the fuel must be extracted from the
fuel tank or a separate, non-pressurised tank (see Figures 6 and 7). This sep-
arate fuel extractor precludes any effect of pressure.
Hole pattern
* Only use a fuel extractor if the fuel tank is made from metal
