I don't have the number but you can buy replacement rubber lines from Napa that are longer than stock. If you want to go that route I would have the parts guy pull the replacement hose then ask him to look thru the hoses for a longer one with the same ends.
Or
go aftermarket. I run Earls brand steel braded hoses. You can get them in many differnt leghts. I bought mine from a local speed shop.
