Fuel Gauge Question

[mattimuss]

[i searched before starting the topic]

 

1.  Before pulling tank fuel gauge seemed to work fine.

 

2.  Pulled the gas tank to have it cleaned.  While out I also checked out and cleaned up the sending unit, hand made a new gasket between the sending unit and tank, and cleaned all electronic connectors.

 

3.  Put it all back together.  Now the fuel gauge reads FULL all the time.  All I have put in is 2-3 gallons of high test.  I labeled the wires when I disassembled and put them back in correctly.

 

Thoughts?  And tanks to all who respond!

have you followed the trouble shooting guide in the repair manual ?? I would suggest you look close at your home made gasket..the sender must be grounded..it grounds to the tank, the tank to the car body, the body to the frame and ultimately the frame to the engine and the engine to the battery

Why high test?

PA:  No, thanks for the reminder.  I put two heavy coats of sealer, two heavy coats of primer and two heavy coats of paint on the tank.  Wonder if I should run a ground strap from the tank to the frame?

 

Don:  I live in CA, better gas, no other reason.  I won't be using it regularly, but did use it for the first start.

I believe I would start with a good known ground and ensure that you have the same on the sender itself...I see where you mentioned the gasket in the first post but not all that good insulator material called paint...

Yea PA, I hate doing things twice.  I had some purty good mentors in the Air Force.  "Do it right, do it once!" was my first supervisor's moto.  It has stuck.  So I usually over engineer everything I do.  And I usually end up doing almost everything by myself.  My wife will help if asked...my daughter has never had grease under her finger nails.  Muscling the tank in and out is one of those pain in the rear jobs that I only want to do "once"!  Also, my tank was in really good shape and I wanted to keep it that way so I made sure there is a good barrier between it and the elements.

 

I finally got the web page built for the '41.  Take a look and let me know what you think:  http://tinyurl.com/ltma2nr

Mattimus;

You can just add a ground wire to the sender itself. I saw this mod as done by Merle Coggins and it was just too easy to pass on it.

Rod:  Thanks!  It has been fun and I know once it's "road worthy" again my girls and I are going to have fun with it.  I manage an IT shop for a living and work on computers, or computer related equipment, all day long.  Working on these classics, with absolutely no computers in them is therapy for me!

 

Jeff:  Thanks for the info, I'll let you guys know if that fixes the problem.
