Fuel Gauge Troubleshooting

Fuel Gauge Troubleshooting
Hey Guys.
I picked up a 2012 Countryman as a project. I got it for a great price even though it has some issues. One of the issues that I am having is the fuel gauge. When I purchased this vehicle, the fuel gauge did not function at all. After, I have replaced the Low Pressure fuel pump that has the fuel level sensor in it. After the install, the fuel gauge did not work. I put 10 gallons of fuel in after and drove home. I started checking the wiring from the pump and was trying to trace it out. After a few hours of that, I moved the car back into the garage to call it a night and noticed the fuel gauge came to life but only showing 70%.
So my question is this. I know on older Mini's there are 2 fuel level sensors. I could not find any information if that was the case here. Also, I am currently search for wiring diagrams for the fuel sensor. If anyone has a diagram that shows the complete route, please shoot me a link. I'd like to find if there is a loose connection or corrosion somewhere.
Also, I had a P144B which indicated the fuel level sensor but that code has not come back since the install and clear. But again, I haven't drove the car much. I have a code for the leak detection pump which will be replaced on Monday when the part comes in. I'll be checking the wiring around that area as well. It would be awesome if the fuel level sensor wiring came around that section. I noticed under the car that the plastic piece that is supposed to cover the pump is broken which could indicate why it doesn't function. I am ordering a replacement piece for that as well.
At any rate, anyone who has tackled this issue or has some insight would be greatly appreciated. I love project cars and as soon as this thing gets all the quirks ironed out, I'll be looking into suspension / build options.

[QUOTE=Socalx;4408470]Maybe. That would be why I'd need a diagram to trace where this runs. I'll keep looking. It's not been a high priority this week.[/QUOT
I know that I saw something like that this weekend, not sure what model it’s for but they are probably very similar..... lemme see if I can find it.

I have not figured it out. I do have it isolated to a wiring issue but I am unsure how the wiring routes from the Low Pressure pump to under the car. It is a bit hard to trace. I feel like the issue is under close to where the Leak detection pump would be but I haven't found a diagram that shows that the wiring dumps to under that location yet. I am still searching.

Has anyone figured this issue out? I recently purchased a 2012 Countryman S and I thought it was the dealer being cheap because I hopped in and it wasn't filled up. The gas gauge was short two carrots.
Drove it around for the weekend for a mini vacation and on the ride back I had to fill up. I went from having like 80 miles left to refill and then it jumped to 30ish and then 9 within 3 minutes. After that moment of being in Timbuktu with no gas I luckily found a station and filled up. It took about 8 gallons before it clicked and I proceeded to try and top off because I knew it wasn't full (I read the vehicle had a 12 gallon tank). Got in the car and sure as hell I was 2 carrots short of being full.
I have been researching to see what my options are but info is spotty and vague.
any info on this would be greatly appreciated
