I believe Dan posted links to the line routing etc. in His post above, so check them out if You haven't had a chance yet. I know it isn't always attractive, but heat sleeve is not
a bad idea on the lines in the vicinity of heat such as what You've got there , if rerouting isn't desired/an option. And always use the least amount of rubber line, even if it is
SAEJ30R9 EFI hose, teflon inner lined or not, it should only be used where it has to be. Definitely NOT over sources of high radiant heat!
