shelbyluvv Posted July 15, 2016 Share Posted July 15, 2016 This is the factory tank out of my 86. Something is off with this tag? Link to comment Share on other sites More sharing options...

Blue88Comanche Posted July 15, 2016 Share Posted July 15, 2016 wouldn't they begin production of the 86 model in 85 to have an inventory of vehicles? Link to comment Share on other sites More sharing options...
shelbyluvv Posted July 15, 2016 Author Share Posted July 15, 2016 The numbers and letters below the date is what is confusing me. Link to comment Share on other sites More sharing options...
Mossmj Posted July 15, 2016 Share Posted July 15, 2016 Didnt they start production july 1 1985 thats what the comanche workers coin says Link to comment Share on other sites More sharing options...
shelbyluvv Posted July 15, 2016 Author Share Posted July 15, 2016 I know this truck is a very early truck. The VIN tells me that. What I was getting at is the tag says 16.0 GAL and that is quite clearly a 23.5 gallon tank Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 15, 2016 Share Posted July 15, 2016 Excerpt from the 86 factory parts manual: Gas, Carbureted 83502635, 1, 23.5 Gallon83502635, 1, 16 Gallon, Also Use 1 of 53002492 Sending Unit Gas Injected83502632, 1, 23.5 Gallon83502632, 1, 16 Gallon, Also Use 1 of 83502729 Sending Unit Diesel83502635, 1, 23.5 Gallon83502635, 1, 16 Gallon, Also Use 1 of 52003644 Sending Unit Notice the 23.5 gal and 16 gal tanks use the same part number and are the same physical dimensions? So it must be an internal baffling thing because the tanks require different senders. Link to comment Share on other sites More sharing options...

Pete M Posted July 15, 2016 Share Posted July 15, 2016 isn't that the case where they changed the vent tube to adjust how much fuel could go in before station pump shuts off? Link to comment Share on other sites More sharing options...
shelbyluvv Posted July 15, 2016 Author Share Posted July 15, 2016 I checked the fill and vent tubes and they hang down about 6" from the top of the tank. Link to comment Share on other sites More sharing options...

shelbyluvv Posted July 16, 2016 Author Share Posted July 16, 2016 This tank will probably end up in the scrap pile. I am making no progress on getting this rust out of it. Link to comment Share on other sites More sharing options...
johnj92131 Posted July 16, 2016 Share Posted July 16, 2016 I checked the fill and vent tubes and they hang down about 6" from the top of the tank. Hey Bo, before you scrap it, give me a shout. I want to play with the tank to see about raising the vent for more capacity like the go-jeep article. Really don't want to screw up my 91 tank with an experiment.
