Does this look like the wrong part?
Had a shop put a new front passenger side caliper and flex hose on about a week ago after the old one started dragging/binding. Pretty soon I realized the new caliper wasn't biting as hard as it should be...rotor on that side running noticeably cooler and truck pulling to the left a touch. Figured it needed a try-again on the bleed job, so I finally got around to that today. Might have helped a little but it didn't totally fix anything and the caliper is still weak. I immediately noticed that new hose though when I pulled the wheel off. It is bending much harder than the one on the driver's side and I can't figure out why other than they maybe used a left side part on the right side. (They are different part numbers after looking at the Rock Auto catalogue and some of the picture might suggest I have a lefty on the right side). It's the correct caliper otherwise the bleeder screw and hose fitment would be on the bottom, and they are marked "L" and "R" where the hose attaches, so that ain't it.

Yes. That part does not look right at all. Both the way the steel part snakes across the landscape partially blocking access to that bolt, and especially the sharp bend in the hose.
What PN did you get?
IIRC there can be brake differences depending on early or late 99. Whatcha got?

It is also possible to twist the caliper and hose during installation. I did this on accident once and did not notice at the time. After the truck was pulling to that side on a test drive, I saw an extra bend or turn in the hose due to the caliper being twisted when placed back over the rotor.
Also, the driver side hose may be different based on the system having a T-fitting where the hard line meets the hose at the top of the wheel well.

Can’t say if it’s the right part or not but one time dad did some brake work and twisted the hose during reassembly (79 F150). Basically the caliper was rolled 360° when installed which twisted the hose. Don’t remember if it was hanging up or not engaging but he noticed it on the test drive.
Just something else to consider.

Looks like the steel part of the hose assembly is installed correctly. If it was flipped over then it would block access to the bleeder. The problem looks to me to be in the flex hose part of the assembly. Needs to be indexed 180 degrees around or something to get it straightened back out. The way it is now, if the suspension gets extended it will pull on it in a self-destructive manner an possibly come apart. Everything needs to be routed like the picture in jstihl's post.

I think Sous hit the nail on the head here, I also made this same mistake and It was on the front passenger brake hose, seeing sous's post jogged my memory. If I remember correctly I had to take the brake hose bake off on both ends and reinstall to get the hose route correctly.
I managed this minor inconvenience by resting the caliper on the frame or other hard parts or sometimes suspending it with a bungee cord. Going to install the caliper, I inadvertently twisted the caliper.
This is why we test drive though, so we are sure.

This is what happened. The hose wasn't installed properly on the fender liner side and it rolled itself into a pretzel. It was the right one though apparently...still not sure why the part numbers are different for L/R side hoses after looking on Rock Auto's selection. They had to replace some hardware on that end but got it sorted out and seems to be working fine now. Surprisingly that was enough of a kink to hinder the braking performance.
We are grateful to hear it is sorted out now and you are good to go.
