93 EFi. My fuel lines are beginning to look a bit tired and I can't remove the current fuel filter - the nuts are rounded and totally stuck. I'm looking to replace both the flow and return lines complete with rubber. Its obvious that rigid replacement is probably impossible with our the body off. The only issue I can see is connecting the new rubber to the steel vertical lines in the engine bay. Theres are the ones wrapped in heat shield and look in very good condition. Has anyone else done this as a complete job and removed all steel lines including these wrapped in heat shield?

Could I just remove all steel lines and connect rubber to rubber at both the tank and engine ends with inserts and jubilee clips? Does anyone know what is the ID of the existing rubber at the tank and engine ends are?

At least then I can insert a new fuel filter in line. Anything else I should be worried about?
