Flex Fuel mounting on NA Chassis

Flex Fuel mounting on NA Chassis
It looks like most people here mount their Flex Fuel sensors near the fuel rail - logic being that ethanol content can change by the time it goes from pump to fuel rail on an returnless system.
I however have an NA which is of course a return style system. I am thinking of mounting the sensor near the fuel pump location as opposed to in the engine bay - is this not a good idea? I haven't seen anyone mount it like that yet, so wondering if I should just go for the way everyone else does it.

Your fuel should stabilize by the time your car primes and runs within the first 30 seconds of you have a return system.... Unless you have an alternate tank your hard switching from.
As Vlad said, save yourself headaches and put in on the supply line. On mine it would drop ~20% at full tilt and do all sorts of weird things with map interpolation.
