I'm running 50/50 WVO/Derv. I'm now on my 3rd. fuel filter. I filter WVO through a 20 micron sleeve. This also removes the fat. What is totally confusing me is when running problem starts ie. won't take full throttle and eventually will stop. I check fuel return pipe from injector pump and there's plenty fuel being returned to the tank. Changing the fuel filter cures the problem. Why should the return be flowing yet replacing the filter cures the problem?
Any ideas, thoughts & theories gratefully received?
