So recently my car started to leak gas from the area under the driver side rear passenger when the car is running. It at a point where the lines connect to the car for like a small turn. If I replace them is there any tips. Should I use Nicole copper tubing or nylon and what diameter are the pressure,return , and vapor line 5/216 I belive. The leaked is right at the area labeled quick connect fitting. I plan to just bypass them since they are mounted to the car. I don't plane to flare the lines, I plane to use pressure fittings. 2000 Honda Accord dx sedan 2.3l 4cy.

 

I'm the most cautious on repairing brake lines and fuel lines in that order. Not being able to stop or causing a fire can hurt you or someone else.

I've never done this type of repair on my cars. I'd recommend replacing the entire line with proper flare fittings, because I suspect you would have other sections that could be corroded. Buying from Honda is the more expensive and simpler option. Using fuel line and bending yourself is an option depending on your skill level.

I remember others saying removing the plastic clips holding the lines is a pain to remove. If you do sections, I'd say use flare fitting as it is designed to withstand the psi from the fuel pump.
