Does it really take so much time?? I asked a Lotus specialist how long it takes to change the fuel pump. They said 5,5 hours... Is this normal?

That seems high. You have a couple options. Remove seats and go through access panel or drop the tank.dropping the tank requires removing lower panels. What brings you to want to remove the pump? I recommend a surge tank if your doing something that requires upgrading the tank. Less trouble and good benefits.

Ziker, reason I ask is, I am playing with the idea to upgrade to REV400. The install cost will be huge, knowing that the rear clam has to come off plus the time it takes to replace the fuel pump and all the rest...

So I just installed the REV400 kit. The fuel pump depending on the year of your car can be a pain to install (so I hear). If its a 2005 its very hard to get the unit out of the tank and you typically end up damaging it (according to BOE it will be destroyed) the replacement pump piece is about 80 bucks. If your getting the rev400 it comes with a new pump, worth about 80 bucks. If you figure your going to break it installing it anyways you can just add the pump and the piece together for $160 bucks savings off of a Surgetank. I only have about 5 miles on my install of the rev400 but I can say its a ridiculous amount of power. But it came at a price. You shouldnt just install the kit. Its alot of work to get the clam off and the kit in. There are other components to think about while your in there. I ended up pulling the tranny for a new clutch, well now that the tranny was out I figured I should do the flywheel as well. and well maybe I should put in a LSD so I did that. It just seemed to keep going. Also... at this power and with access to the engine I decided to do my valve springs,retainers and seals. The only concession I ended up making was a low cost header setup. Its DEFINETLY better than stock but not as good as the higher priced options.

After looking at your post I see that you already have many of the support mods to go along with the increased power. I say add the surgetank. I like the added comfort and ... I think I can go an extra 2 miles with all that extra fuel tank space.

When I was getting my REV400 installed at BOE, I was told that the stock pump is retained (not removed) but effectively set to 0 pressure - as a pass thru- that feeds my surge tank. So I don't think you need to remove it - just turn down the out put pressure some how? And leave it in the circuit?
(Editorial note: I do not know for sure, I only know my recollection and i had consumed a couple of micro brews.. the entire event may have been night terrors...)

Oh now I've done it. I probably got it all wrong.

5.5 hours seems reasonable.
If you were planning on the pump and/or swirl pot... Then another option is a fuel tank.
ELise-parts or Yvo's Elise-shop is close to you.
The swirl pot adds complexity, weight, and number of parts, but it is cheaper.
Since the time and labour also counts, I would suggest you study up on the best solution.
While I prefer the tank option, most people would suggest spending krona the on power mods.

I just did mine Sunday. It was about 4 hours including the modification for the larger pump and the access port hole increase. That's on a non 2005 or 2006 which were supposedly harder. It was done from behind the drivers seat. Also it's a purists addition, so maybe there was less interior crap to fuss with. I'm also taking my time..
