I read somewhere that it will work, but will only show 3/4 tank when full - due to the ohm issue Soyuz008 brought up. Don't know though? For more ideas look at: http://www.ford-trucks.com/forums/1052846-mustang-tank-under-bed-questions-1955-a.html and http://67-72chevytrucks.com/vboard/...a51a01739963d3b&t=396325&page=2 and http://www.trifive.com/forums/showthread.php?t=21578. Good luck, when you figure it out let us know please, because I have to address the same issue at some point. Thanks.
