Grounding a Seding Unit

Grounding a Sending Unit

I'm getting ready to install a new gas tank (one of the non-pourous versions ), and I need some advise on grounding the sending unit.

I've heard the ground is very critical in having a functional gas gauge. I'm painting the new tank, and the interior of my Jeep has paint. So, I'm guessing that I won't have a good ground through the body just by contact. I don't think drilling a hole in the tank is a good idea either, so how do I get a good ground???

TIA!!!

 

Negative. I should have mentioned that. It's a locking-ring style...

 

If you really want to do it right, get a solder lug with locking teeth and sand off the paint where it contacts thte body. Cinch it down tight with the right size screw. Use a similar arrangement at the sending unit end, or solder the ground lead directly to the sending unit. You'll need a big iron to do that, something like a Weller soldering gun.

I think I have some lugs - I'd be happy to send you a few.

 

Like Brian said, I would try to solder a wire onto the tank and then you could paint over it.

If that would work how about a stainless self tapping screw with some fuel proof sealant on the threads?

 

i was thinking the same thing about the self tapping screw, i was just skered to say it

 

Solder is the way to go! Don't put any holes in your sending unit.

Pretty simple - you need a big iron, a length of wire, some good rosin core solder, and non-corrosive paste flux. Pick the location where you want to stick the wire, like the smooth top surface of the unit. Apply some paste flux and heat up the metal. When the metal heats to where it will melt the solder, make a little puddle of solder on the surface. The metal has to be hot enough so that the solder starts to flow out - a good bond. Now take the tinned end of your wire and place it on top of the solidified puddle. Apply the iron to the wire till the puddle melts and the solder flows into and around the end of the wire. Let cool and done!
