This was my first conditional inspection since I purchased a 2 yr old ELSA from another fellow.
This is one inspection I don't totally agree with. There was no annual requirement to do the same with my RV-8, and I assume the same applies to the other RV models. The fuel strainer screen in the RV-12 is coarse. It would take one heck of a contaminant to block the screen. Plus I don't like messing with loosening and tightening the fittings on soft aluminum fuel lines. Lastly, I care not to deal with the potential risks associated with transferring fuel, and I am not a fan of sticking anything electrical into a fuel tank.
I do exercise extreme care when filling the tank to include holding a clean rag over the filler neck while fueling. During the condition inspection after inspecting the gascolator screen I disconnect the fuel line at the mechanical fuel pump and conduct a flow test.
From an operational standpoint, get familiar with your fuel flow during takeoff, climb, and cruise. Any pressure fluctuations may also be indicative of contaminants in the fuel thus warranting further inspection.
During my six years of ownership of the -12, I have inspected the main tank screen twice to check for contaminants and found none. Of course if contaminants were found at the gascolator that would be cause to inspect the main screen.
P.S. I assume you have the split aft baggage compartment bulkhead panel. If not, you will have to pull the tank anyway for the condition inspection to check the security of the the right flaperon attachment fittings under the floor boards.
