Gas gauge troubleshooting

Speaking of earth at the sender...is a hose clamped wire to the hose spigot acceptable? Mine goes straight to flexible hose from the sender, and Im starting to look why mines not working too...
The factories ground jumper simply snapped onto the metal fuel lines to create a ground path over the short piece of neoprene fuel line there. Two hose clamps with a piece of wire could be as good as original if hose clamps hold the wire tightly. A length of braided ground strap will fill underneath hose clamps, serve better than small stranded wire.
