I used a brass hose barb that screws into the plastic female end on the tank (wraped with teflon tape), the female fitting that goes to the engine is a chrysler type and can be found in just about any boat shop, they even have them here at Iboats.
I just want to point out one thing I have learned about the Ted Williams, the smaller the fuel line diameter the better the fuel pump element will work, I think 1/4" was stock, I did however use 5/16 fuel line and it works fine as long as the tank is not to low.
