Need help with the fuel line

[Alex Rositano-fox]

Ok so the lines are leaky and rusted, got a new set off lines to go, just looking for some help as to how to get the the areas where im gonna need to get into too be able to do this, thank you

p.s I am new to cars, mainly a motorcycle kinda guy and it defiantly isn't as simple as propping the tank up and shoving a rubber line in lol (from how I see it)
