Got a 98 civic EX coupe. Finally got my engine back together and running good. So I take it for a test drive and brakes are weak and I notice a puddle. Look underneath and 2 hard lines are leaking all rusted out. My question is I have 5 lines front to back. 2 are brake, 2 are fuel I assume but what is the last line for.

 

Charcoal Canister that vents back into the gas tank so you dont smell gas.

 

2 brake lines (L+R rear), 2 fuel lines ( 1 feed, 1 return) and the fifith is from the EVAP Canister to the fuel tank.
