| Subject: | Flying Again....after Kreem Problem |
Just a follow-up (search/see Kreem problem again post). I removed wings and "sloshed
out" flaking off Kreem with MEK and then re-sloshed with a 50-50 mix of
Kreem and MEK. If anyone wants the details on how I accomplished this, feel free
to PM or e-mail...not necessarily a difficult task, but there were a lot more
things to plan and consider than I first thought. As recommended in the forum,
I replaced the existing fuel lines (the mil-H-6000) with automotive R-9 5/16"
tubing and here I made a mistake that nearly cost me an off field landing.
I thought I was as careful as I could be to install the fuel lines exactly as
they were before(I'm not the orig builder) since the plane had flown 133 hours.
The difference is that the new tubing is much softer and flexible, but more
subject to "pinching off" if a bend is too narrow. Bottom line, the left fuel
line pinched off behind where it comes thru the fabric and was not supplying
enough fuel to keep the engine running, so when the right tank got low, then
engine sputtered and would have quit(about 7 miles from airport). At this point
I didn't know why I wasn't getting enough fuel, the sight gauge in the left
tank showed plenty, but I realized the right gauge did not, so I put the plane
in a nose high, right wing high slip causing the remaining fuel in the right
wing to flow to the outlet going to the header tank which allowed me to make
it back to the airport. After landing, I inspected the system, folded the left
wing, and discovered the "pinched fuel line". Even though I thought I was being
careful and double checked everything when I re-installed the wings/fuel
system, I obviously made a very stupid mistake, and am posting this just on the
chance that it might save someone else a similar problem. Thanks to everyone
here that posts as this forum has been extremely helpful to me. Paul Perry
