Going to be mocking up the fuel lines soon and need a location where to mount a factory flex fuel sensor. I have the LS3 with the tanks efi tank. So I will have a short run from the tank to the reg/filter then a run from that to the front of the car. The reg/filter has a return on it. I'm thinking of having the filter no more then a foot or two away from the tank and would like the sensor back there also.
