Its very easy…take the 4 screws that hold the gas lid…take out the rubber piece that’s around the gas filler and you’ll see where the gas lines are… disconnect them and the electric plug… undo the bolts and pull it out…its something like that its really nice

It's a 20 minute job, at most.
May as well spend another 30 minutes and clean your sending unit to ensure that finicky gauge stays accurate for another 20 years.
Here's how.
You'll be washing your hands before you even get the second beer finished

Make sure you wire it right though. First time I did it I had to do it 4 times before it worked right. One time the float got tangled going in the the gas gauge stopped working. It is very easy though. While you've got it out check the condition of the rubber hose that goes between the FP and the metal lines. It can sometimes crack and leak without you noticing and cause a loss of fuel pressure.

the relief valve regulates pressure created by the pump. a relief valve cannot create pressure. the size of the line cannot create pressure. the pump creates pressure overcoming resistance encountered moving fluid through line or other components. pumps are fixed displacement with a set pressure rating, some are pressure compensated with variable flow. in any case, pump produces flow and creates pressure. no other component can do this.

Depends on the pump. Some are variable some are fixed. What about hydrostatic pumps?
That's the only test in your post that is correct. You may need to dust off your text books from school. The fact is, the biggest, baddest pump in the world, pump 1000 GPM of oil (or any liguid) won't generate a single PSI unless there is something applying resistance to the pumps out put. In the simple fuel system in a car, it is the fuel pressure regulator that both applies the resistance, and governs how much of it (pressure) there is.
I know one thing for sure, based on what you POSTED (hopefully what you typed isn't what you meant)...I wouldn't let you touch our fleet of hydrostatic drive, $250,000 snow cats w/a 10' pole. A hydraulis engineer? Yikes!
This is getting interesting.......

the pump is still the only component in the system that can produce pressure. a relief valve will protect and open at preset cracking pressure. a system (pump) can operate and produce pressure without a relief valve in the system if it was removed.

last time for me. if you take a simple logsplitter circuit that has a pump, tank, valve and double acting cylinder only and NO RELIEF VALVE and make it operate the cylinder the pressure and flow made by the pump will show on gauge. as cylinder increases effort ( work ) pressure will increase. since there is no relief valve to create pressure as you say, what is making pressure ? the pump, the only component that has the capability of doing this. have a nice day.

" resistance to flow creates pressure" which is one function of the pump. the hose, the fitting the whatever else cannot create pressure, only the pump.
