After having the flush the fuel tanks a number of times, I had to check and clean the fuel filter quite a few times as well.
One of the frustrating things is that while loosening the fittings, fuel would squirt, or trickle out around the fittings. Because of the shape of the fuselage, the fuel would pool on the flange. I tried my form-a-funnel and every other trick that I could think of to no avail.
So I decided to build a couple Fuel Filter Removal Diverters (Patent Pending).
