Volvo Repair: fuel lines from fuel distributor to fuel injectors, inner diameter, volvo 240

Question
Car specs:83 Volvo 240 Turbo 2.1,L4. I need to change the fuel distributor to fuel injector fuel lines,is there anything other than slow pressure release,pinching off lines,and keeping clean that I need to do to do this job correctly and safely for my fuel system?And,can you tell me what size(inner diameter)those lines are so I can buy them before taking them off?

Answer
I have not worked on many old turbos so I am not very familiar with them.I do not see any real special needs other than to be sure they get put on the way they came off.as for the inner diameter this is not information we would have in our literature since we would use the volvo replacement.I would try searching the www.brickboard.com there is alot of old volvo info here
