    Default Time to change out all of the fuel lines...

    Hey guys, first of all apologies if this is a repetitive problem- I have searched long and hard but a few questions remain unanswered...

    Here's the situation- I leave work yesterday to find a puddle of petrol under the car. Not good. I've had problems in the past with a corroded fuel line and had to do a temporoary fix due to lack of funds/time at that point. This time its sprung in a new place, right at the back of the tank where a rubber hose meets the metal line. If i'm honest I'm not sure the rubber hose that is there should be or if its been bodged before?! Anyway I get it home reverse it onto some ramps (scratched the underside of the bumper in the process because its so low) and Syphon pretty much all of the petrol out of it and store it (I put £50 worth in the night before... Typical).

    The good news is I'm off work for two weeks now and have got some cash to throw at it so I'm planning to remove the pump etc, disconnect hoses/pipes, drop the tank (PLASTIC), and get a good look at exactly what pipes I need to replace. Questions:

    1). Do I definitely need to depressurize the system? If so why?

    2). Will I have to disconnect the battery or will I get away without doing it? I didn't for fuel filter/water pump etc.

    3). There are two main hard lines what is the better option - getting the steel ones from the dealer or getting some copper ones purpose made? I need to take into account durbility/cost/ease of fitment etc etc. If i go with copper ones I need the dimensions too (i.e how long each section is before bends etc), i've seen them somewhere on this forum before but just can't find them.

    4). The two main hard lines (and breathers etc) are horribly corroded at the back end, but from the centre of the car forward they seem fine. Is it best to cut and join there or re-do the whole thing? I only ask because getting the lines in through to the engine bay seems like it could be tricky.

    5). Should I replace the fuel pump while I'm there? I don't know its history but don't currently have any problems with it and not sure on the price yet. Looking into it.

    If anyone has done this before or can offer any advice or tricks of the trade I'd seriously appreciate it. I need to get this job done I've been procrastinating for long enough... I'm taking the car on a 500 mile trip in August so its gotta be tip-top.

    Many thanks in advance.
