Changing out the gas tank and lines on my 57, Not sure if this is the right forum for this question but here it goes. I bought the kit from Ecklers with tank, sending unit , oring gasket, etc... The 4" estimated hose length and around 1-3/4" diameter that connects the 2 filler tubes to put fuel in the tank was brittle and cracked. I can order one from Ecklers for around $25. Does it have to be a special hose? Could I use use a section of a radiator hose with the right ID? Probably cheaper and I don't have to wait a week or more for shipping.
