In the past Diesel Giant said that if you use new Hose you are going to get several years of use. If keep your old Hose it may leak soon.
The regular auto part stores have 5/16" Fuel Injection Hose SAE J30R9 or 30R90 (SAE 30R7 is the Regular Fuel Hose.)
The Fuel Injection Hose is lined with what members have said is Viton.
That leaves the Injector Return lines and those can be taken care of with Viton Hose or some members have found the Gasoline powered Weed Wacker Plastic Fuel Line holds up.
One of the members used:The brand I used is Oregon (like the Chain Saw company), it is a Tygon fuel hose. Tygothane (Saint Gobain is the Manufacturer). He did not mention what inside diameter he used.
I have not read anything that has the Cigar Fuel Return Hose getting eaten up by Biodiesel; so, I do not know if that happens or not. 5/16" Hose should fit there.
