Good stuff, Guzzle.
I already have a couple of them - the in-tank (Hutch) mod and the coolant bypass (I used Evans coolant). I gotta get the relay on mine.
Good to see you included the Harpoon mod in the Hutch mod piece. Major PITA reduction for zero bucks and whn doing the Hutch mod is the time to do it.
One refinement on the Hutch mod. I did mine in the winter and found the tank cap ring fits better if you microwave it for a minute. Caution: It will be hot but it runs down easily and fits fuel-tight. If you don't the tank cap leaks a little.
