If you replace the fuel pump the fuel level sensor is part of the unit. I installed new fuel pump unit and still have gauge problems. Shows empty when plenty of gas and also still have the P0460 code - which says 'Fuel gauge sensor A37'. The hardest part of the job is getting the stupid plastic fuel line connectors off.... they work differently than you think. https://www.youtube.com/wat... . you MUST watch that video before you go to pull the old pump... you WILL destroy the little plastic pieces. Save you the money for buying new fuel lines ;- ). Good luck
