Matt,

Remember that the return line is positioned after the last pump=20 and before the mixture control valve so that the mixtrue control actual= ly=20 controls the mixture (and pressure) actually reaching the=20 spider. If I had such a return line on my Lycoming, it would not=20 affect my flow sensor as it is located between the throttle body (after mixt= ure=20 control) and the spider. In the Skymaster, fuel pressure,=20 measured from the Gage port at the spider, was displayed as fuel=20 flow. =20
