What kind of fuel pressure do you like to see with your ETB?
Has anyone out there ever found that an ETB was causing any over temp problems (i.e. running too lean?)

ellison throttle body - fuel pressure

I have an Ellison on an O-320 in an RV4 with Van's filter set up. No problems in 230 hrs. Fuel pressure is 4 to 6 lbs with engine pump, goes up a couple of punds when boost pump is on.
Very good fuel distribution. It can be slowly leaned to stoppage and the engine never runs rough. EGT's within a smalll margin throughout the whole range. I just wish it was OK for Mogas.
