I used to work in Mobile Install for Best Buy and, to be gentle, we probably wouldn't do it that way. You need to insulate that ground. Don't remember what the stuff is called, but get some of the black gummy stuff that is used to hold window water shields in place in car doors (and no, electrical tape won't cut the mustard here). Just take a wad of it and smoosh it over the ground connection to the sheetmetal to avoid a fire hazard. Make sure to apply plenty and cover the whole connection. If you stop by any decent car audio install shop, they'd most likely just give you enough to do the job without charging you. Be prepared when you get it to either put it where it needs to be immediately or have some way of keeping it from touching anything. The stuff sticks to everything and is stubborn to remove from any material it touches.
As for the power, I suppose you could do that, buy why? I would splice into a hot wire elsewhere under the dash. There should be plenty of power wires that you can T off of. Just find a power wire, remove the insulation where you want to T. Take a pick and separate the wiring in the middle so that you now have an "o" in the wiring. Stick the uninsulated end of the power for the gauge into the "o" and then wrap it around the "o", effectively clamping it closed. Wrap the uninsulated area with electrical tape and then join the first two or three inches of the gauge power to the hot wire using small tie wraps so that they can't pull apart. Taping off of a fuse like that sounds like trouble to me, not to mention being a real rig job. Any auto electric tech would just close his eyes and shake his head if he saw that.
I'm not trying to knock what you're trying to do. It looks like I'm going to need a FP gauge very soon too in order to troubleshoot a hard start problem. Hope this helps.
