Looking for the best way to store a fuel cell to get the longest life out of it. I only race 1 or 2 weekends a year, some years not even that so it sits a lot. My last one only lasted 6 or 7 years, the one before that went 11 or 12.
Here's the options I can think of.
1) Full of fuel (currently has ethanol free pump gas in it).
2) Drained
3) Drained, rinsed and allowed to dry with openings open, then closed up after fully dry.
4) Full of fuel but with AVGAS
5) Any other suggestions?
