Yep, it is just a bolt. But it is sort of critical, since there are only three bolts holding each hub to the knuckle. If you don't replace it with an OE bolt, at least use one of equivalent strength, thread pitch, and length.
In theory it is possible. BUT... the fuel line is plastic, so there would be issues with how the connections between line and filter are made. The fuel system operates at around 58 PSI, so a leak proof connection is essential.
There are also liability issues if a shop were involved, these...
If you really want to change the filter, you have to replace the fuel pump module (that is, the fuel pump, sending unit, and filter all together in one assembly). This involves dropping the fuel tank, and is the reason there is no fuel filter maintenance in the schedules for maintenance.
I don't know about affordable ducks. The only ducks I have had are ones left by strangers, that I give to my wife to give to children in her classroom when she substitute teaches.
Lots of trends going sour. Over ducking (duck pond on dash)is one. Angry grilles are one that is out of control. But the worst is Jeep prices, and parts prices, going up out of sight.
I worked in an aviation support shop years ago. One of the guys had a Chevy truck with a front tag that said "Like a Rock" that he had a guy make for him in the sign shop. It only lasted a few days before it was replaced with a near duplicate saying "Like a Co_k". Took a while for him to catch...
If you don't see an obvious leak point on the EVAP system, you will need special equipment to diagnose it. Cold weather always brings out these issues with the EVAP system, seals harden and leak, hoses crack, etc.
The P0456 DTC indicates a small EVAP leak detected. The battery doesn't cause this DTC, it results from the evaporative emissions system self test. On some 3.6 Pentastar engines, the purge solenoid hose cracks near the connector, which causes a leak resulting in the P0456 DTC.
The "U____"...
Take two of the original steering gear bolts out and thread them in from the steering box side far enough to locate the box (hanging it on the frame) while you remove the two remaining bolts. Slide two new bolts through the bracket, using the two holes that will not line up with the two bolts...
This is just low effort trolling. Getting people excited about the Hurricane engine. I'll make it far simpler than any of these trolling posts can. YES, the Hurricane 6 will fit in a Gladiator. NO, it is not coming in the '25 model year. Probably not coming even later.
I got my "come along winching" lessons about 40 years ago. That Power Wagon was a beast to pull out using a come along. I probably would have a heart attack now if I had to work that hard.
I know what you mean about memories. My shop foreman says my job title is "3.6 Headmaster and Keeper of the Arcane Knowledge". I always make time to help the youngsters, but they usually also get a dose of theory to go with how or why something works the way it does.
