Thanks Rpman, I have spoken to Marcus also but like you are not completely convinced. I have a older landcruiser which is very robust but of simple design. My concerns are based around the idea that glowplugs are not designed for this purpose/ wvo being injected into a cold engine/hot wvo going into a cold ip. My plan would be to only use the glowplug heaters during the startups. When the engine comes up to temp a coolent flat plate heat exchanger would then take over providing the fuel heat as the glowplug heaters are thermostat controlled. Marcus does not have the fphe in his single tank system kit but I'm going to add this to take pressure of the glowplug heaters and the power draw required to run these heaters. The injector pipe heaters would cut in and out as required to maintain the correct temp at fuel injection. Marcus has a nissan patrol which he converted to a duel tank system. He added his injector pipe heater system later and started using both tanks for wvo. Marcus claims to have used this system for 12 months with no problems.
The benefits of the Australian climate help greatly but is it enough to stop hot fuel shock to the ip pump? Reading the horror stories about breaking pump shafts etc from this is a concern to me. The other main concern is injecting hot wvo into the cold combustion chamber at startup. Will there be ample burn to stop carbon build up on the bore walls/ piston tops and ring gaps? Will running a blend of say 10-20% dino deisel with the wvo ensure a clean burn?
Once again thanks Rpman for your comments and I would be intrested to hear more about your conversion and how its going since we are from the same climate/ state etc. Also I would still like some others from this forum to comment if they have the time and/or intrest. Like Rpman I am open to purchasing a single tank system from outside Australia, froggo.
