The fuel systems in full scale jets are completely different than r/c jets. For one, full scale jets do not use the fuel as a lubricant unlike r/c tubines do. I'm not trying to bust ur ballz, just making an observation. I for one will not use sumpted fuel until someone at Jet Cat (in my case) says it's ok to do so! That's all.
Bottom line...full scale jets filter and pump fuel to the engine exactly as we do with models but on a much larger scale. The fuel controllers are different but the actual fuel system is very similar. Also...we do not use fuel as a lubricant; we use the oil which is added to the fuel to lube the bearings. A small amount of fuel is diverted and sent through the bearings to accomplish this.
I always know where my jet-A comes from. Still...I filter it with a "MrFunnell" before I add turbine oil. That removes ANY water and impurities from the fuel.
