Internal pipe work added to second fuel tank to act as a radiator.

HEATED SECOND TANK
This is the modification required to be added to a second tank in order to heat the oil and make it less viscous. The perspex panel was installed to enable viewing for prototyping purposes. At this stage anything can go wrong!!! (A slight leak was fixed later.) The panel is hinged in case the WVO is more solid than expected so it can be "shovelled" in.
