Had my 2019 Fusion 1.5 with 245 miles to the dealer about loud fuel pump sounded like a box of rocks! Dealer said they all sound like that !
well I bought a New pump from Ford and installed it.The fuel pump tappet was fine .cam looks good.
sounds a little better but the engine has more power I order a hood pad and a fuel pump sound insulation housing
from a 1.6 engine.Also installed an Engine cover.
