I have now been making a few fuel line and sort of got the hang of of it.  It seams easy but it's fidderly too. 
  So mark out your pipe and cut with either a grinder or big metal cutters 
 Put tape areound befor you cut it helps to stop it from slaying out 
		
		
	
	
 I have plastic coated braided hose. So I need to cut that back about 6-8mm 
 The fittings are for teflon hose . 
 Make sure you have the right fittings for the type of hise your using. . The teflon ones have this olive to seal against  the tubing 
 so started off  take your tape off and slide the nut over the tube . Then open out the steel braiding. 
then slide the olive on down to the shoulder of it
using the special tool to open out the tubing to make sure the fitting slides in is this special tool
you can get all differnt ends for different size and fittings then slide the rest of the fitting in to the tube 
all the way to the end 
 then I bought these ally clamps to not scratch the fittings that fit on to the vice 
 Also these ally adjustable spanners too also so they don't scratch. And then tighten
