My KR2 has a 12 gallon center tank and also 6 gallons in each wing. The airplane flies with a Revmaster 2100-D.
Prior to the KR2, my only experience with gravity feed was in a J-3 seaplane. I have a 4 PSI free-flow pump on-hand, and I am considering installing it as a 'booster' pump for unusual attitudes, low main tank level, etc. Something to give the carb. a constant pressure... Has anybody tried this, or are there any thoughts about this? Thanks! Dave.
