Rubber is rated for 275F. Metal braid for 350F. Your block is not running anywhere near 275. You will be boiling over by 250.
Metal braid is typically used in high pressure applications or in locations where abrasion is likely. Lehman ran a short length of hose behind everything creating an abrasion risk. I ran mine outside and used loose tie wraps to secure it.
It is easier to just remove any oil coolers or heat exchangers to allow access to fuel pump. Good opportunity to clean them out and replace cooling hoses. Not a lot of room to swing a wrench.
