dmartin_egroup Posted August 8, 2018 Report Share Posted August 8, 2018 My dash unit was showing zero while driving around with a full tank. I connected a jumper wire from ground to the sender wire that goes to the dash, this made dash unit read FULL. This meant sending unit is bad, so I removed sending unit. The cork float is heavy, too long soaking in fuel. Mainly the sender reads 200 ohms regardless of float position. Are these senders repairable? Please, I would like to hear from folks who have actually fixed one with their own hands, not just someone's theory or day dream. Or, has anyone bought a replacement sender?? Dennis M. in W. Tenn.

Ranger Posted August 8, 2018 Report Share Posted August 8, 2018 I replaced mine in a '36 Plymouth but also replaced the tank with a poly unit from Tanks Inc. I doubt a sender can be repaired. My original was pretty crusty and the cork float was water (gas) logged as well. Just didn't look like a good candidate to try and salvage when replacements are available.

Depending on the skills fairly everything can be repaired. I have fixed mine in reality and it works like a dream ?, see http://p15-d24.com/topic/42339-plan-b-–-what-if-parts-are-not-or-difficult-to-get/ #23 Edited August 9, 2018 by PT81Jan Quote Link to comment Share on other sites More sharing options...
mmcdowel Posted August 14, 2018 Report Share Posted August 14, 2018 I bought a new one from either Roberts or Classic car auto parts....have to dig through my receipts to remember which. Came with a brass float....worked perfectly and a quick swap out. Be sure to take all safety precautions during the install. Quote Link to comment Share on other sites More sharing options...
dpollo Posted August 14, 2018 Report Share Posted August 14, 2018 Chrysler part # 2240729 is a sender for auxiliary tanks and was available through the 80s and 90s. It fits and works perfectly with only a float arm adjustment. It would be worth a try to see if any are still available. I have one in my 35 and used one in a 38 with good results.

desoto1939 Posted August 14, 2018 Report Share Posted August 14, 2018 You might want to Contact Max Merrit. He is a Packard dealer that I know can repair these sending units. Max is located in Indiana near Terre Haute. I have know Max for over 20+ years and he does great work. Also do a search on Atwater Kent. They are also making new sender units.
