If they have sharp bends in the hoses you will have to get formed hoses from mercury or you may have problems a regular straight fuel line restricting your fuel from the bends.
Also that grey line is known for deteriorating, I didn't know they made a different one (3000 & 4000) I only use automotive "fuel line hose" & have recommended it also.
