Re: [AMC-list] Swapping out fuel sending unit - where do you connect ground?



A toothed washer (preferably one with teeth on both the inside and outside) between the ground terminal and the the body will help with contact as well. I'm about 90% sure they put one there to begin with. On both my 67 and 68 Americans the screw goes into the same crossmember that the J bolt goes into. Make sure to leave some slack in the wire so you don't pull the wire out of the terminal from vibration.

Yep - yellow wire. No new wires run. I should have been clear.

Car is on jack stands. Battery is disconnected. Wire to the fuel
sending unit is disconnected. Fuel line is disconnected. J-bolt is
loosened. Front-end of gas tank is on a jack stand, back is still on
the strap. Hopefully it will be warm tomorrow at lunch time - so I can
swap out the fuel sending unit (and pick up a sheet metal screw).

That's probably not a good ground; Joe's suggestion of drilling a hole and
using a self-tapping screw is probably best. it needs to be connected
tightly to clean, bright metal. A squirt of spraypaint on the screw, wire
and metal when you're done will keep water and corrosion out later.




  I just connect power to the sending unit, and
then the ground wire to the body somewhere, right? Re-connect the
battery and cross my fingers?

By this I assume you mean connect the (yellow?) wire back onto the sender in
the tank, not some separate power wire... you'll likely start a quick and
serious fire i you wired 12V onto the sender. The sender is connected
(through the harness) to one of the terminals on the gauge, only. Just
double-checking.
