Fuel lines, thread sealant?
Are you suppose to put thread sealant on the fuel lines where they connect to the TPI fuel rail?

Like Ed said, no sealant. These are "o-ring flare" setups and use the o-ring to seal the connection. Also, make sure you use the correct o-ring. They MUST be fuel line o-rings for that application. Using regular o-rings from Pep-boys or so could cause leaks.
