Fernando, I have never had any problems with the pumps at all since the K80 was introduced, neither have any of our long list of customers for that matter... there is nothing generally wrong or to be concerned about from my experiences with the stock K80 fuel pump as supplied from Kingtech, to insinuate otherwise would be misleading in my opinion. Any component on any turbine can obviously potentially fail at any time there is no track record of the K80's fuel pump or injectors being a concern more so than any other popular brand turbines. It is easy enough to check your fuel pumps smooth strong flow rate by simply plugging it directly into the ECU battery for brief running period ie 10sec with fuel lines in/out connected and submerged in bowl of kero so as to not run it dry, this would obviously eliminate the pump as potential cause. Refer to Page 18 and Page 25~26 in the K80 owners manual for pump adjustment referrence. Iam actually using a six cell 7.2V 2400mAh NiCd battery on my K80E and have not had any of these problems. Anyway Let us know how you go...

If this problem is 'infact' traced back to a a clogged fuel injector that would be the first time I have heard of this occuring with any K80... Iam sceptical at this stage that this is the cause and that it would actually be an injector, its possible but unlikely.

If your problems persist and fuel system does not show any apparent external visible restrictions after checking fuel line and fitting size's for blockage, vent line is open when running, no air leaking into fuel system including pump and all ECU parameters have been double checked as I previously suggested (pump flow rate checked). I would then recommend to send your K80 back to Kingtech for further factory inspection, they will take care of you very quickly and solve this concern. As a newly purchased K80 from Kingtech repairs or component replacement is of course still fully covered under the manufacturers warranty. Hope this helps....

Cheers- Marty
