The fuel pump should take less than 4 hours if you've never done it before. Pretty straight-forward:
1. Remove rear lower seat cushion
2. Snip access
3. remove retaining ring (this is the most difficult part, a little penetrating oil helps a lot)
4. Pull pump assembly from tank
5. Pull pump from bracket
6. Shove new pump into bracket
7. R-insert assembly into tank
8. Button up
I don't like sharp edges, so after I bent the access flaps back I covered all my little cuts with duct tape and re-installed the giant rubber grommet that goes over top. Easy - really.
Two notes:
1. Get a nice pair of snips at Home Depot. Under $20 and make the cutting job VERY easy & neat.
2. I had never done this in a Contique and finished the job in good time - with breaks.
