Marty, I am happy to hear you have such trouble free experience with the original KingTech pump.

K-80E that is shipped out after December of last year will come with the newer version of the fuel pump. One of the most important improvements is the increased stability of gears and shafts relations. This improvement takes the reliability of the older pumps to an even higher level.

Concerning the suspicion of the clogged injector(s), is the fact that there are different petroleum refinery standards and additive requirements worldwide.

Fernando, let’s rewind a bit, back to the pictures you sent. Although I am not suggesting it is definitely the cause, but those plastic ties are really asking for trouble especially if you aren’t double looped (double looping ensures 360 compression). If you look closely enough, the single loop like what you have will pinch the soft tygon tubing and often cause a leak. Perhaps that explains the air/fuel level in your UAT.

Anyway, I hope your K-80 is flawlessly back in action with your beautiful Velox sooner than later, as I have the exact same plane, same scheme, and of course, same engine.

All the Best,
Barry
