The injectors are fairly simple to remove, carefully disconnect the spill pipe along the top of the injrctors, unclip and tie back the electrical connection to the injectors, now unscrew the feed pipe to each injector ur removing and then unscrew the injector clamp, the clamp screws should be unscrewed slowly as the threads tend to be coked up. The injectors should now lift out with a little bit of turning from side to side. if they are tight and hard to move, you can spray some alloy wheel cleaner around the neck of the injectorand let them sit for a few hours, even overnight, the new seals..copper washers ..and make sure u get the modified ones .. should be fitted making sure the seats are clean and free from debris and the injectors clamped down again. dont overtighten the clamp bolts and if ur using the same bolts clean the threads with a wire brush before refitting them. Your other problem the container under the car near the left wheel I think that is the air con tank u are talking about

The fuel cooler is there to cool the fuel on the fuel return line, the fuel gets very hot after passing over the injectors.......best advice would be for you to re-connect the cooler.
