thanks for your input. Since my question, according to a video on youtube , the santafe 2007-2009 requires the rear 60/40 seat to be removed. the driverside has the fuel pump & sensor & the passanger side had the 2nd sensor & they recommended replacing both sensors at the same time,not the float but the switch/wire assy(sensor) which are actually potentiometers.if the video is correct,the fuel sender lock tool is needed to remove the cover of the sending unit. If you hear of anyone who replaced these sensors on the santafe,plz forward any info, thanks
This is correct, but you don't need the lock ring tool. You can use a hammer (use a big hammer) and a flathead screwdriver or chisel to remove the lock ring. You may need a razor blade to cut the carpet a bit to get at the sending unit covers.
Make sure you depressurize the system before you remove the fuel lines or you'll get sprayed in the face. Pull the pump fuse or relay and run the car until it stalls.
All the hose fittings are quick disconnects. Two of them should have locks that need to be removed. There's also a crossover tube that connects both sending units in the tank that has to be disconnected.
The sensors are locked in place by a tab. Depress the tab and they slide off.
Dorman has a kit for this job that comes with both sensors and new seals.
