the hose from the outside of the unit to the external pump is called fuel injection hose and is easy to get at the auto parts store. however be careful with the small hose that goes inside the tank and connects the intank fuel pump to the metal tube out of the tank on the sending unit assembly. this hose is a special type that resists deterioration from fuel. remember that hose is submerged in tank fuel. gates makes the hose(called submersible fuel hose and it is available from napa. you only need a short piece. it is expensive. forget the number something like 30R9. dont use regular fuel injection hose or fuel emission hose. it will deteriorate to mush in a year. see if someone on the forum has a piece of it left over. good luck oldduke.
