zetec Posted November 10, 2011 Share Posted November 10, 2011 I want it out to carry out a chassis tidy up. is it straight forward Link to comment Share on other sites More sharing options...
Drumster Posted November 10, 2011 Share Posted November 10, 2011 Just done this as I've swapped from a carb tank to an injection tank. It will come out the top of the boot with the FIA bar in place. 1. Remove boot floor and the aluminium strip the divides the boot in half 2. Undo all connections; sender, fuel hose, retaining bolts & anything else I've forgotten 3. Jack up the rear of the car, you'll need extra ground clearance for 4. below 4. Now you should be able to move the tank to one side, tilt down towards the diff and it should now be in an upright position to lift out between the rear supports of the FIA bar. Job's a good 'un Link to comment Share on other sites More sharing options...

Drumster Posted November 10, 2011 Share Posted November 10, 2011 ....and another thing. In these Elf'n'Safety days I suppose I must advise you to remove the petrol first 😬 Link to comment Share on other sites More sharing options...
rj Posted November 10, 2011 Share Posted November 10, 2011 "does the fuel tank on an S3 come out the bottom?" No. Link to comment Share on other sites More sharing options...
zetec Posted November 10, 2011 Author Share Posted November 10, 2011 i'll try it on a live axle car & let you all know Link to comment Share on other sites More sharing options...
Eugene Posted November 10, 2011 Share Posted November 10, 2011 Had my tank out a few times... Live axle, and it comes out the top. Link to comment Share on other sites More sharing options...
Angus Posted November 10, 2011 Share Posted November 10, 2011 I have had my tank out through the bottom a few times. Much easier than the top. Remove rear boot floor section, disconnect the filler pipework and breather, loosen and remove the retaining stap and bolts. Lift one end and tilt the tank and manoeuver it out downwards. Car is S3, metric and has the 'Sigma' tank with the fuel pump assembly mounted in the top. I didnt even need to jack it up or disconnect the fuel hose or electrical connections !

OliverSedlacek Posted November 11, 2011 Share Posted November 11, 2011 I'm going to contradict Angus and say "No". Surely an S3 chassis isn't metric? Link to comment Share on other sites More sharing options...
LesG Posted November 11, 2011 Share Posted November 11, 2011 I'm going to contradict RJ and say 'Yes'. My car is an '85 DD S3, and I swapped from carbs to injection tank and removed/replaced tank from bottom. Link to comment Share on other sites More sharing options...
Garibaldi Posted November 11, 2011 Share Posted November 11, 2011 Yep... Taking the tank out of my injection 94 S3 is done out the bottom.... Remove as much fuel as possible.... electrics, return line and pump supply. jack car and place high on stands. I use some masking tape to seal inlets/outlets. Lift tank - move to left - drop right down through chassis until return pipe hits DD tube. Adjust tank position so you can tilt tank aft to allow return pipe to clear DD tube. Job done.... Refitting is reverse of removal..... as they say Gary Link to comment Share on other sites More sharing options...
Roger Ford Posted November 11, 2011 Share Posted November 11, 2011 Mine definitely wouldn't come out the bottom. I tried for a long time (someone having told me this was the way to do it) but the various sticky-out appendages (sorry to get over-technical) made it impossible. Rotating it and lifting it vertically out between the roll cage bars worked though. Link to comment Share on other sites More sharing options...
Angus Posted November 12, 2011 Share Posted November 12, 2011 Thats interesting. There must be differences in the tanks that prevent some from being removed downwards. My car is a 2007 duratec, S3, metric chassis. The tank removes easily from the underneath, there is no 'wiggling' required. Link to comment Share on other sites More sharing options...
catastrada Posted May 13, 2012 Share Posted May 13, 2012 I add a point : i need to remove the tank from my DD S3 (imperial chassis). The 2 "brackets" that are below the fuel tank are fixed on my car. A friend of mine has a R500 D (metric chassis), and those 2"brackets" are removable which make a differnce... Link to comment Share on other sites More sharing options...
James_Russell Posted May 13, 2012 Share Posted May 13, 2012 Quoting Eugene: Had my tank out a few times... Live axle, and it comes out the top. Yep, and not without prior removal of rollbar/cage in my experience. The live Axle chassis is different to the De-Dion so the posts about De-Dion cars are irrelevant.
