Gordon, may I suggest you take a look at Michel's web site:

http://mthobby.pcperfect.com/ch601/chowings5.htm

About half way down the page he shows his approach to grounding the tank.

I intend to do the same.

Gordon <cscsail(at)gmavt.net> a crit : 



Thanks for the input. I replaced the split paper washers and I have no leaks, as long as I don't put a grounding lug under the screw head. The washers I was provided are made of a thin gasket material with the integrity of heavy paper, and can only be snugged, or they will split.

The problem I see with using these sending units is trying to ground them properly. The units appear (when checked with an ohm meter) to have good continuity between them and the grounded tank --without a grounding wire and lug under a screw. ...

Grounding contact is definitely a problem with these

senders.  I found that the little tab (as shown in

Michel's photos) was not making a good contact with

the plate.   I ended up welding the leg to the round

plate and this solved the problem.  It was when I was

learning to gas weld and this was a perfect

application.  Here's a photo or two:

If you are getting good contact now, there is a chance

that in time the connection could get loose and lose

continuity.  That's why I welded it.  



I hope this helps,

Had the same problem with my senders. I put a small dab of sealer on the

treads and voila no more leaks. Do not put sealer on the last few tread at

the end of the screw or it will get in the tank.
