Hi, iv just been running a power wire to my boot as iv decided to relive my days as a chav haha and install a sub in the boot, whilst doing this I come across 3 think wires that go from the front to under the back seats and curiosity has got the better of me so I thought I'd ask what there for?

 

Fuel lines

 

Ah! Nice one. How come it has 3 runs rather than 1 and split at the engine?

 

One feed to the engine, one return and one vent.

 

Dont be running the power cable across them.

 

Iv re routed them down the other side, glad I asked now, thanks for everyone's input!!
