I've been following the various red cube threads for a couple weeks, but can't decide how/where to install my fuel flow sensor on a RV8 with a Lyclone engine.
Basically, it seems that these sensors are very susceptible to heat and vibration. In fact Vic Syracuse, in his most recent EAA webinar called out a couple of installations that had it mounted to the engine mount as a potential source of failure. So I'd planned to put it on the firewall with a heat shield between the gascolator and the engine driven fuel pump with a teflon/SS line from the cube to the engine pump, all uphill.
On the other hand, when I opened the package yesterday, the instructions from EI said that it HAS to go between the "last fuel pump" (i.e. the engine pump) and the carburator, otherwise it may lead to vapor lock and inaccurate readings.
I can live with iffy readings, but vapor lock got my attention.
How has everyone with a non-fuel injected set up done it, and how well did it work?
