Fuel Gauge Grounding

[JimM]

Can the fuel gauge sending unit be grounded through the locking ring since it is secured to the tank and the tank is held in place by the metal strap? I don't have the clip which attaches the sending unit to the steel fuel line so I am looking for an alternative approach.

Thanks, Jim M

Theoretically it already is....provided there isn't a build-up of paint between the J-Bolts that secure the tank and the body anchors that they pull on. The jute/insulation pad between the tank and the trunk floor provides more electrical insulation than conductivity, and the rear mount provides little contact to the body. You could take a multimeter and measure the resistance between the lock-ring and body to check it out. Never tried it myself, but if it proved to be under 1 ohm, I would think that would suffice as a grounding. :icon_thumright:

You should have a solid metal to metal ground, factory is the fuel line because it is held in place with metal clips along the frame edge. but you can screw the wire to the metal body if you want.

You could replace the clip with a piece of wire and a couple of screw clamps?

He should be able to use some #18-12 solid wire just strip the insulation off and use small hose clamps and screws to mount it. will be fine.

My Tech Ted @ Valaya Racing in San Jose says it was a bad ground. Not the ohms, not the sender itself. Owned the car since 1988 and have never seen it read full before. Ever.

Was it reading empty all that time?

No, would not go past 2/3. Always worked, but weak.
