Duster fuel filler pipe difference between years

The pictures were mine and I still have caps. I also have a 72 fill tube.. The 72 slips through and screws to the quarter. All earlier years the flange is on the inside and the quarter screws to the tube. You need one with three holes not four. Four holes are for Darts and scamps they have a different bend and will **** the quarter hole causing a ripple.

72 is the easiest to get a cap for. 71 good luck . 67-70 take a none vented cap the tube has the vent built on. If you cannot find one in your area let me know.

The picture of the dart tubes are 71 next to 72 note The 71 tube will not seat on the outside of the quarter and the holes are clocked different. Same with the three hole Duster Demon. Switching to a different tube there is more involved then some realize
