Tired of spending 20 minutes getting that last 3 or 4 gallons in the tank at the station? The Harpoon Mod is a simple proceedure of cutting the vent tube and filler tube off as close to the tank wall as possible. This allows more fuel to enter the tank before the foam backs up through the fill tube and clicks off the pump. This mod should be done when your are also doing the In-tank Hutch mod since you have to drop the tank to get to the internal tubes.



To keep from getting pvc shavings or saw "dust" in the tank, use an inexpensive PVC pipe, ratcheting cutoff tool. They can be purchased from local garden shops, Wal-Mart, K-Mart or Harbor Freight. By reaching into the tank and placing the tool next to the wall of the tank, you will be able to cut the tubes off to about 1/2" in length.


After cleanly cutting off the tubes, just reach in the tank and pull the tubes from the bottom of the tank and discard them. Here is a shot of the vent tube and fill tube shortened.

The Federalists Papers, Number 57, written by James Madison:

....... in the situation of the House of Representatives, restraining them from oppressive measures, that they can make no law which will not have its full operation on themselves and their friends, as well as on the great mass of the society. This has always been deemed one of the strongest bonds by which human policy can connect the rulers and the people together. It creates between them that communion of interests and sympathy of sentiments of which few governments have furnished examples; but without which every government degenerates into tyranny.
