Questions on a 1973 Winnebago Brave D-20

the motor is it a 413 or a 440 both being dodge motors, really looks and sounds great, like I said i miss mine, but wifh and myself live full time in our fifth wheel and well need a bit more room than 20 feet, the fuel sender is going to located on top of the tanks, easy to drop and remove, if you get them out and take an ohm meter reading on them while moving the float, if the meter moves it might be the gauge, you can always just replace the senders and the gauge with after market stuff, the 10 year thing is not always enforced but it is still on the books, they mostly go by the way it looks when you pull into the campground
