I replaced my factory 35 gal. tank with the intank lift pump assembly with an Aerotanks 60 gal. tank, new sending unit (which worked before I installed it) and a FASS. I had to remove the harness that the dealer installed for the intank lift pump in order to hook up the FASS harness. Now my fuel gauge doesn't work? Anybody have any ideas? I really don't want to drop the tank unless I have to.
