Does anyone know what are the typical GPH flow rates of the return line of the ECI Titan EXP fuel injection system at idle, cruise and full power settings? The engine is an IO-360.
Also can the ECI system be run with the return blocked off completely like other brands of FI systems? Or does the ECI system absolutely, mandatory, must have the return line free-flowing at all times in order to function correctly and not experience some kind of overpressure condition?
The reason why I'm asking is that I have a friend who's installing one and he's insistent to only plumb the return to one wing tank only, which I think is going to make fuel management a hassle if the return line's flow rate is significantly large.
If the ECI system can tolerate the return line being shut off completely and still meter fuel properly, then the single tank return could work with a simple inexpensive shutoff valve inline to prevent overfilling that tank and blowing large amounts of fuel out the vent when running off the other tank. That would still give the option of manually engaging the return to help cool off the system for hot starts when switched to the tank that has the return line plumbed.
