If I measured correctly the new tank is not any deeper I think it is just longer, but I think the float level might have to be checked. From what I understand from Dodge mechanics and the parts guys it should be just "plug and play"(which it never turns out that way) We'll see
I found out today that the 26 gallon and the 32 gallon tank use the same Module Fuel Pump. The only changes in the setting are done with software and the dealers do not have access to that particular software. I really don't care about the accuracy of the DTE but I am concerned about the fuel gauge not being accurate. Maybe I'll put the tank in with velcro so if I have to take it out and put it back in a couple of times it won't be such a pain in the ***.
Pedro--I talked to the OP and he said he still does not have a resolution to his problems. Thanks for the link!
Completed the switch to a 32 gallon tank. The 32 gallon tanks from 09 through 13 are the same although the part number changed in 13. The Module
Pump is the same for the 26 gallon and the 32 gallon and all the straps etc are the same--basically plug and play. The gauge seems to be accurate so far. The DTE seems to be a little off right after you fill the tank but it becomes more accurate after you drive about 50 miles??????I don't know why. The dealer does not have access to any computer software to change the computer from a 26 gallon tank to a 32 gallon tank.
Cost--If you buy a new 32 gallon tank they sell for about $690(list price is over $900). If you buy one from a wrecking yard they cost about $300-$350. Dealer install is around $100 bucks or you can do it yourself. If you change it yourself, the least amount of gas in the tank the better. Takes about 2 hours to change it out.
