There's risk in life. I've had more close calls driving on I-5 to/from work than I've had in airplanes.
I've been working on the engine and fuel system, Rotax recommends a gascolator before the fuel pumps and I've bashed my way into a concussion banging my head trying to figure out a way to put one in the narrow confines of the SeaRey's fuel compartment. I've come up with a few ways to do it, but the hard part is maintaining and repairing it afterward. I'm sure there's a way, maybe, eventually, but after a year of working on it off and on I've decided that I'll accept the risk of not having a gascolator before the fuel pumps and stay with the standard SeaRey method of a fuel filter in the compartment, then a gascolator downstream on the root tube later on as others have done.
Installing is easy, but there will be a non-openable window where when she's flying, and I won't be able to get in this way, instead any access will be via the very narrow quarter circle behind the seat.
