Analog fuel guage and EIS in Parallel?

BillC

Well Known Member
I am thinking of using the GRT EIS-4000 but I would also like to have two fuel guages next to the fuel selector valve as visual reference to actual fuel in tank while making tank selection. Has anyone done this or know of someone who has? I know that the EIS needs to be calibrated as part of the installation and should be able to be adjusted for the effect that the meter may have but, will the EIS cause the analog meter to be out of calibration?
