I've been trying to source a fuel sender for my EFI XE falcon. I know EFI XF's had the same unit but they are almost impossible to find. Has any one had any success fitting and EF or similar Fuel sender into an XE or XF sedan tank.

The Later Style senders are a completely different type of sender and wont work with your XE/XF electrics. That said, I have an EB Sender on my XF with the NC Digital Dash. its just thinking about how the sender is mounted - and as a bonus if your good with steel then it should be easy.

have you considered modifying an XE or XF standard sender to fit the EFI mount?
