inserted in this line. The fuel feed to the engine will be from the other side of the “tee” and a lubrication take-off comes from the branch of the
“Tee”, which supplies a small amount of fuel to the bearings. Use clear piping for fuel pipes so you can see the fuel flowing, which will help your
starts stay smooth.
The small Hausl ZP28028W fuel pump is suitable for the MW54 and is supplied in the kit package. The output is up to 3Bar @ 250ml/min. Higher
capacity pumps will have to run slow to give a suitable idle of around 50ml/min and may make the engine unstable and have difficulty in getting
smooth and controlled starts, so are not recommended.
A tank capacity of 1Ltr should be sufficient for a run of 6-8minutes. Oil should be added to the fuel, to a ratio of 3% oil to 100% fuel, that’s 33:1, or
30cc of oil to 1Ltr of fuel. Use oil to grade TCW3, or alternatively turbine oil can be used. If you opt for turbine oil be careful not to breathe the
fumes as they can be harmful to health.
A propane/butane or pure propane bottle is connected to the gas connection via a regulator or suitable tap connection – gas blowlamps have the
valve and connection all in one and are useful for conversion! A cheaper option is to purchase a ready-to-fit gas tap, available from Wren Turbines,
which simply screws onto the gas cannister. Note the gas supply must not be liquid gas so
do not
use a cannister with a dip or flop tube.
Check that the starter motor turns the engine with NO rubbing and that all your batteries are freshly charged. Fuel up your tank and we are
ready to go!
