Hi All, When I flew the Quicksilver MX, I had an in flight fuel pump 

failure. The MX used the Mikuni, rectangular pump. After that failure, I 

started rebuilding it every other flying season. The little flapper valves 

always looked wrinkled and in need of replacement. When I built the 

Firestar II it called for the dual round Mikuni pump. I continued with my 

bi-annual fuel pump rebuild, however, the parts I replaced always looked 

like new. I am thinking a rebuild every other year is overkill. Any 

thoughts before I order a rebuild kit? Thanks in advance. Lanny

Lanny/Gang:



I guess you could stretch it to three years if two years is an overkill.



Let us know if you have a fuel pump failure between two and three years.

I have gone over 7 years without a pump replacement (rectangular). They are reliable and this is a good thing. During the last 3 years, I switched to a round Mikuni dual pump and tied the output lines together. I don't have any plans to change it.

I had one in a  Phantom for 7 years...260 hrs  never touched it...but that should not be a  benchmark for your re-build time.

  

 Mark...Ultrastar  with 60hrs and counting
