How long to replace rear fuel lines?

Hi,
i have just noticed a fuel leak from my rear fuel lines on my RRC 3.9efi.
The lines are pretty corroded and need relacement asap. I would do this myself but i am buggering off to West Africa tomorrow for a month.

I will need to get the local 4x4 garage to replace them for me as i dont want the wife spilling fuel everywhere.

Can anyone tell me how many hours this job should take so i can get an idea of how much i will need to pay to get this done (i hate paying when i know i could do the work myself!!!!!)

Cheers,
Stu.

No one?????

You can't use a book time for them (because there isn't one listed in the RTS) so it would not be easy to estimate.

The second problem is that I doubt you can get replacement parts, so they will have to be made up for you, adding to the cost.

Not a cheap one, I feel.
