Fuel pressure sensors
I just installed a set of fuel pressure sensors on a pair of HP500 EFI's. The pressure registers fine at idle but as soon as I touch the shifter they go right to zero. The sensors are both grounded to the transom assembly and there's just a sending wire that runs up to the gauges on the dash. Anyone have any ideas?
