Fuel connections
The standard length of the fuel hose is 4 m (max 8 m). Cut the fuel hose to a length suitable for installation.
The lift height of the pump should be less than 2 m; preferably 0.5-1 m. The fuel pipe must always have a Wallas filter.
The fuel filter can be installed either near the device, near the tank, or in another location where it can be easily
checked and replaced, when necessary.
Diesel engine fuel filters and/or separators are not approved for use. All soft connections should be made with rubber or
silicone hose which is resistant to fuel. When joining with rubber connectors, tubing ends should butt against each
other.
Connection to a heater
Use pliers to hold the pump inlet elbow steady, while you tighten the 12 mm fuel line nut. The joint has to be very tight
to prevent air leaks.
Tightening torque is 19Nm(14ft/lbs).
Country-specific requirements
The standard fuel hose is plastic. Please observe country-specific requirements with regard to the material of the fuel
hose/pipe and the fuel filter. The inner diameter of a new replacement hose should be equal to the inner diameter of the
plastic hose. Copper pipe 300692 and metal filters 30016 are available as accessories. Ask local requirements from
your distributor.
Fuel feed
If the lift height exceeds 2 m, the fuel feed must be checked and, if necessary, adjusted.
The fuel feed must also always be checked, if parts of the fuel system, such as the pump or the electronics card, have
been replaced. Fuel system adjustments are device specific. These adjustments should only be carried out by an
authorized service shop.
Connection to a fixed tank
The device must have a dedicated connection with a fuel filter outside the tank.
Connection to a separate tank
Cap run-throughs and sintered filters are used on plastic tanks. The fuel tank should be mounted securely.
