"The 182E also featured electrically-operated "Para-Lift" flaps,
neoprene rubber fuel bladders holding 65 gallons total, new stronger
main landing gear/fuselage attachment and improved nose wheel
steering."

Looking at the 172R specs on the Cessna web pages, the wing tanks are listed
as Integral fuel tanks, 53 gallons useable, 5 quick drains per wing. No
fuel bladders in this model, it would appear.
