It would be, but it's also very troublesome getting the whole line, and fit it on the car... The way I looked at under the car, it seems impossible to fit the whole thing without bending part of a prebent line by accident...
I'm going to borrow my friend's measuring caliper, and find out what size the line is. It seems that one of the two line going to the rear had bubbled up near where the fuel filter is.
