2017 Ford El ticking

Since I put the premium fuel in it the ticking has quiet down.

I have a 2017 Ford Expedition with a 3.5 Ecoboost engine at around 60k miles and I am getting this loud tick as well. It seems like it is always ticking and the only time I cant hear it clearly is when the fan kicks on. The check engine light is not on and i am getting very good 18 MPG fuel economy. It just drives me crazy because I do not hear it in other similar expeditions wit this same engine. Thank you for the suggestions above. I will get it booked in with my Ford dealership and see what they come up with. Will keep you guys posted.

It’s the high pressure fuel pump. Idle rpms it’s around 400psi of pressure being pushed through. It can be up to 2600psi. This is normal sound
