Darren , Yes ( on the heatin and filtering of used veggie oil), but…. Beneath that general understanding it gets a lot more complicated…Heat and filtration works in a 1985 mercedes. but is really problematic in the newer tdi's .. someone mentions use of caustic to reduce the free fatty acid content.. a poor mans biodiesel or ? How is it pllied and removed or do you remove it? Point is , the heat of course can come from the radiator with a line-within-line, or a wrapped line system but that does not reduce the free fatty acid content --and the issue being the acid which pits the injectors and can rot out ordinary rubber hoses. We will be seeking out the slower running, near bulletproof, single lung Lister type thumper for the conversion: Its relatively easy to the conversion: The question is; what is happening 6 months down the road ..We need to crack that nut before recommending it to our friends up in the usambaras and we are going to be there in one weeks time-
