02 to 07 Fuel Tank Swap

[bennybb]

I have a 2007 9-5 with the typical fuel level sending unit failure. I'm pretty unhappy about GM changes (I hate GM now!) that require the tank to be removed for servicing the pump and sending unit. I'm scraping a 02 9-5 and considering swapping fuel tanks with my 07 as it accomplishes two tasks. First it fixes the sending unit and second it modifies it to be serviceable from under the rear seat. It looks like I'd have to modify the wiring a little and the lines, I'm good with that. What I am concerned about is if the older and newer fuel sending units send the same voltages to the DICE or cluster? I thought someone might have chased this rabbit down the rabbit hole before so thought I'd ask. Thank you! Dale Bennion, Roy, Utah

The simple answer is to check the part numbers of the fuel pumps using EPC. If they are the same, no problem, if they are interchangeable also no problem.

Thank you but they are both 12 volt fuel pumps, that's not my concern. My concern is if the fuel level sending units both sent out the same voltage. The earlier ones, 2005 and earlier, don't have many failures and seems like 2006 and later all fail.

As the transmitter is part of the fuel pump, if both are the same p/n you will be fine.
