The copper pipe was the flexible stuff like brake pipe,I also soldered the olives too just to make sure they stayed in place,as for the steel pipes from filter to engine I used a flaring tool and put a flare on them (in situ) to help hold hoses on ,make sure you buy high pressure fuel hose,not the stuff designed for carbs, I had to do mine because it developed a leak at tank fuel pump ,just as it comes out of the pump on the 90 degree bend ,so when I installed the new one I covered all the metal pipes at the pump with copper grease ,so it might last a little longer,don't fancy having to drop the tank again anytime soon good luck a lot cheaper than £ 220 odd quid
