Last year I replaced my old steel gasoline tanks with plastic ones. The new on-board tank came with a new hose and priming pump.
What an improvement. No more rusty/oily rings in the starboard under-seat hold. An added bonus is the on-board tank has a reserve section that should get you home if you forget to top off the tank. You simply tilt the tank toward the filler cap and a reserve of gas sloshes over a barrier and into the gasoline pick up tube area.
I also purchased a 5 gallon transport tank which I fitted with a hand pump nozzle. It makes refilling the on-board tank a breeze. The hand pump nozzle looks like a miniture gas station pump nozzle. You position the transport tank above the level of the on-board tank, lift the air inlet lever and give the nozzle a few pumps. The gas starts to flow and a siphon tube that runs down to the bottom of the transport tank continues to allow flow until you release the trigger handle. It makes topping off the on-board tank quick and easy with no mess.
These were both West Marinehttp://www.westmarine.com purchases.

I'm working on a fix for the gas guage. The float sinks in gasolene causing the guage to always read empty.

The gas nozzle on this model snapped off when I accidently bumped it against the seat hatch.
