It seems to not be a serviceable part or so the technician said when I went to Ford today. It's part of the whole fuse box under the driver access panel inside the truck. That is really weird. If it goes bad you have to replace the whole part which is I have attached. https://www.f150online.com/g/album/5277211

The information you were given regarding the relay is correct as far as a dealer is concerned. They will simply replace the whole fuse box.
It is not difficult to splice in a common Bosch-style relay externally to the fuse box. I know I've written it up somewhere as have other forum posters, either here or at sister site FTE.

Do you mind explaining how to splice the Bosch-style relay into the box?

Before picking up another part or tool, connect a test light to the pump power feed located at the inertia switch and check for power during the initial power-on priming cycle.
You need to know which half of the truck to focus on, otherwise you're going to continue pi$$ing away money and time just trowing parts at it and hoping you guessed right (again).

See where I said "I know I've written it up somewhere as have other forum posters, either here or at sister site FTE."? That means someone is going to have to find it back (not me).

Glad to be a part of the forum. I'll post any success.
