external fuel tank
« on: April 14, 2008, 04:36:02 AM »
I want to use a 55gal drum to fuel my lister.  If i mount it above will it have too much pressure to the fuel system?  Do i need to place it on the ground and use a probe in the fuel tank?

The entire tank needs to be above the fuel injector but if the viscosity of the fuel is thin, i.e. store bought diesel oil, then the lowest head need not be more than a few inches.  A head of 48 inches above the pump will not overhwhelm the pump.  Placing the 45 gallon drum on it's side will reduce the pressure fluctuation from full to near empty and allow you to use the existing bung holes for filling/vent and outlet.

Dursley used to sell a fuel tank of around 10" diameter x 24" high which was used "on end". That would be pretty close to a 44/55 gallon drum on its side.

I've just looked it up.... Dursley manual says not more than 6ft above crank. Is that top or bottom of tank? ???

Cheers,

Brian

I would take that to mean the fuel level (head).
