Which Fuel Injection Lines are the best?

[rickjames8]

What hoses are missing when you purchase a 9 piece set as opposed to a 13 piece set? Of those, are the 9 the most vulnerable, or the remaining 4?

It wasn't until someone mentioned to me the other day that these were original, and a potential hazard, did I even consider it. I'm not concerned with engine compartment appearance, just want to be safe.

Also, would a car that has been garaged and driven more that having sat, be more or less prone to failure?

Here are the line other 4 lines in no particular order:

#10 feed line from the fuel filter

#11 return line to the tank

#12 inlet to frequency valve

#13 outlet from frequency valve
