REFLECTOR: Bendix RS-10B1 problems

I think the inlet from the servo body should be at the same side of the diaphragm as the gauge and all the nozzle lines...... It looks like it is on the top side of the diaphragm...

Subject: REFLECTOR: Bendix RS-10B1 problems

All, After being rebuilt for three years I finally got to start my IO540E1A5 engine today, but I have a problem with my fuel injection system not regulating the fuel properly. I either have the system pluming wrong or my RS-10B1 servo unit has a blown diaphragm. The only way I could get my engine to run was to remove the servo to flow divider line and manually adjust the mixture to air ratio using the throttle and mixture controls in the cockpit. Once I got everything just right, it ran like a champ.  With the RS-10B1 servo to the top of the Flow Divider, line connected, the pressure from the servo unit servo output would push the top diaphragm down so hard, that no fuel could enter the flow divider and thus no fuel could get to the injectors. I have attached two photo's showing what my units look like, and details showing what I believe each connection should be. This injector system should be similar to an IO540K. Can someone help with getting these connections correct, photo's would be nice, and if as I am suspecting, that I do have a blown diaphragm, who do you suggest that I use to get my unit bench tested and repaired. I am hoping not to have to pay for a full overhaul, this unit only had 300 hours on it after its last overhaul, when I purchased this engine. Andy EllzeyN151AJXLRG
