Dave...I don't want to make it sound easy...but your issues are small and relatively easy.
Which hose is the "upper"? I'm about to replace the piece with the orifice tube in my neighbors car. It's a serious pain to get at..but overall there's worse out there. Only have to move the master cylinder and abs, then scratch the hell out of your arms to do it.
Fuse..there is definately a fuse for that pump. If it's not a fuse, it's not horrible to change the pump.
Gas gauge.. I swear to you... I changed the level sensor on her car faster than she could change the headlights. That's right.. 4 10mm bolts took her longer than for me to swap the sensor in the tank. I was done in under 15 min.
Grab some parts and tools...spend an afternoon with your car and you'll have all these items fixed up quickly.
