The new rangers have a cover/insulator over the high pressure fuel pump.

Hmm - So the 3 questions are.

How much does it reduce the noise of the HP Pump?
It is worth the investment?
Will the cover hold heat (internal) to the HP Pump and be a detrimental factor in the electrical function of it? Even though it has (cool) fuel running through it, it may make it hotter by encasing the heat from the engine. (just a thought) and wonder if engineers tested this theory.

We can always turn the fake engine noise back on!

Saw this on Facebook where someone noticed the new rangers have a cover on the high pressure fuel pump. lt supposedly fits the 19-23 and drastically reduced the pump noise. It's made of the same material as the engine cover. Might also p
rotect that area from the famous drip onto the engine.

It's the sewing machine sound you hear - more pronounced at (Cold-Engine) Start.
If you take a mechanics stethoscope and place it on the HP Pump housing, you will know what everyone is referencing.
Is is audible? Yes
Is it annoying? Somewhat but (NORMAL)
Will a cover muffle some of the sound? Yes, but to a point of not hearing it (to a tuned ear) most likely not - it's only going to slightly reduce it.

I'm curious enough to get one but,
https://parts.ford.com/ says it doesn't fit my '22.

I would do that but I need several sounds to select from depending on my mood.
Supercharged 5.0
The Fart sound.
Poorly running Model T.

Just priced it at several places $85 list, and found it for $60 shipped to my home. I'll pass and listen to the sewing machine.

Where $60 shipped?

Will it involve the dealer drilling a drain hole into the engine block?

The pump itself has a cover. It's the same material as the engine cover. I can see it on my 2019.

It's this....

Since it's directly on the pump, maybe it's there for protection from heat.

Looks like they use the same vendor that molds the bump stops.

I never actually looked closely at mine until today, we do have a cover already, but it appears they either removed this one or they installed the (new design) cover over the existing cover and bracket.
Bracket Purpose? - Protect the pump is my guess.
I hit it with my Stethoscope and the bracket actually enhances the sound (makes it resonate)
so, I am thinking they added the cover over the top of the whole thing to tamper down the resonation as I cannot see engineers removing that bracket.

Is the pump really that loud?

I can't recall ever really hearing the fuel pump on mine while I had it. Only times was if my head was near it.

Otherwise all I heard was the typical turbo charger sewing machine noises from the topside.

Funny- the only sewing machine noise I get is from the stock exhaust system?!
