I just got the latest RVator in the mail today and Van's discusses the situation with Precision Airmotive getting out of the carb business. While they leave open the possibility that there were be success with Precision selling off its carb business, the article also seems to imply that a lot of people who were planning on going carb might consider going with fuel injection now, particularly since apparently almost no one is currently selling any new carbed engines, including Lycoming. The article then addresses some of the fuel pump and cowling issues associated with making this change.
This makes me consider, more and more, switching from carb to f.i. while I still can (about ready to order engine from Aerosport and have note done much FWF). I'm sure that someone will step in to continue to make carbed engines viable, maybe even in the near future, but I'd like to know fully what my options are and what the ramifcations are in switching.
Thus, a couple more questions to help me learn more about fuel injection systems:
1. Do all fuel injection systems require a fuel return line? If so, where are these shown on any the drawings? Or are they? I haven't seen reference to this yet, but maybe that's just because I have a carb FWF package with its associated drawings.
2. Is the gascolator eliminated altogether? If so, why?
3. Assuming you have enough juice in your battery to run the f.i. fuel pump, but not enough to get the starter engaged, is it possible to hand prop a fuel injected engine?
4. Are all fuel injections systems entirely independent of the aircraft's electrical system once the engine is running? (e.g. will it run if alt/bat is lost in flight?)
Thanks for the help.
