First off it seems as though it should be one line and not two. Also looks to have hose clamps and no other hoses have clamps like that.
The shorter bigger section is some piece of goodyear hose and the fluid (water?) seems to be finding its way in between then material as seen in second pic. Lot even sure what that metal piece that is inserted into larger hose is.
Longer stretch is fuel line.
Something seems not stock here.
