The two parts of the fuel system are isolated from each other. Are you replacing the secondary side lines, aka, high pressure lines? Sorry, I choose to not do Chinglish.
Plus, I don't have a clue what engine or tractor you're talking about.
Not all tractors or engines are the same.

Hi Bob, thanks for the reply. It is a Foton 404 (490BT diesel engine)
The parts manual calls them sebific ducts but they are an “s” shaped
rubber fuel line that ties the injectors together? They are dry rotted
and cracked and fuel is leaking down the side of the engine block.. I'm trying to figure out how to release the pressure so I can change all 3 hoses.

If they are the S shaped hoses , those are on the return, no pressure on them

Tommy is correct, those are the fuel leak-off lines from the injectors (on the primary fuel system side). Some engines also run the return fuel from the injection pump through these lines back to the tank, in which case you'll get a lot of fuel there.
Tommy has your new hoses.
