What should it cost to replace the fuel pump and filter on a 1998 Mercury Mountaineer?

no more than 125.00 for labor or buy the book it's not that bad. Try to avoid the dealer mom & pop shop with a good rep do better work. and they don't treat you like a number. the fuel pump is about 160.00 new after market.anything under 300-250 is fair. but shop around. Good luck
