Lotus Turbo Esprit S3 (and similar) fuel tank replacement "The easy way"

I received this procedure from Theo Linschooten who owns an '85 Turbo (the procedure may vary slightly for other Esprit models). Thanks Theo!

Editors Note: Travis tells me that on the 1990+ 4-cyl models there is a lot more to be careful with the ECU and all of the sensor wiring. Also, the rear trunk and the side firewalls have to be removed.

This procedure takes around 4 hours to do. and a little bit less to reverse, in total 6-8 hours.
Quick Synopsis
Before you begin remember to disconnect the battery!
  1. remove gas struts
  2. take away both trim panels on the side.
  3. remove right hand seat belt reel cover
  4. remove seat belt reel (keep it in up right at all times or else lots of things will fall out of it!)
  5. remove air intake stuff.
    1. airbox to turbo hose (on the airbox side)
    2. breather to airbox hose
    3. airbox cover
    4. air filter
    5. airbox
    6. adaptor to sidewall hose
    7. the inlet scoop
    8. air scoop
  6. remove the fuel hoses
    1. return hose, at the fuel presure regulator side
    2. refuel hose and inlet pipe (there are three hoses connected to it...)
    3. tank to cross over pipe hose
  7. remove tank to body setscrew (also holding the earth cable) and then remove the vacuum gizmo thingy (dont know the name on it... step 7.5)
  8. remove the fuel tank top board
  9. remove the tank board to bulkhead bracket
  10. remove the right hand gas strut to cabin bulkhead bracket
  11. remove the rear engine bay wall/floor (you might succeed without doing this by bending, but beware...)
  12. remove plus cable to start motor
  13. remove the engine bay sidewall
  14. lift the tank
The removal procedure can be done within 4 hours of work if doing it right and having a car hoist to easily work underneath. It will be very difficult and risky trying to drain the fuel tanks with just a car jack. Putting it back will take around two hours.
First of all you need to drain the tanks, but to eliminate many times of hoisting the car start with 6a. Hoist the car and fix a hose and a steel pipe with the inner diameter about the same as the hose to fuel pump. Put a bucket underneath and jam the hose to the fuel pump. insert your drain hose into fuel pump hose and drain into a can.
Beware when draining the cross over pipe as it contains quite a lot of fuel. Don't try to just pull the hose of as you will have two streams of fuel coming out having more preassure /speed than expected. Just drain it slowly by just removing it a little bit and then pushing it sideways letting it drip dry. To speed things up you can insert a screw driver or similar if it doesn't have any sharp edges.
As you are now probably already underneath the car go on with procedures 6b and 7 (tank to body set screw).
Then lower the car and go for 1 to 5h.
The fuel tank top board is mounted wheel housing with two bolts and at the bulkhead. Luckily the nuts holding the wheel housing bolts are welded to the plate mounted at the backside of the top board, this means you only need to be at one side. This also counts for the bulkhead bolts who are welded on a steel strip and putten through the bulkhead from the drivers side.
Normally you do not have to remove the drivers seat and back panel infront of the bulkhead to remove the tank, the picture is just for giving you an idea how the bolts are mounted at the other side.
7 to 11 is quite straight forward...
12 is a bit more tricky though. After removing 10 by the 3 bolts to the left and right side of it, you start with lifting up the right hand side a bit first then you turn it sideways to the left a bit so it will go free from the left hand gas strut bracket. Then slowly lift the front side (the bulkhead side) slowly uppwards to release it. The problems you may encounter is that some POs sometimes use some silicon addeshive which makes it stick quite a lot to the body. Beware to use to much force. When sliding it over the engine you shouldnt need to use to much force either. Ok its a bit jammed but if its to tight you arent doing it right.
15, the final lift. This one is very tricky. First you will have to lift the front part, then you need to turn the tank towards the engine and slightly backwards while lifting it. Beware of your side window as you might hit it when removing and mounting the tank. put a bit of cloth at that side of the tank to protect it should it hit the window. As this lift is quite technical, I have created a simulation using two different formats to make you get the basic idea of it all.

To get things back again, simply reverse procedures. and final picture:
Beware! The sucker who fixed my fuel tank, and in the end made me having to get it out a second time, had used some silicon sealing to seal the fuel meter. This ended up both pressing silicon into the tank when tightening the screws who also pressed round parts into it as they had silicon on their tips. This repair did cost me more than three towings,one big hot water flush through the tanks, and more than 20 hours in the garage.
Have fun!
