Special Tool(s) : 303-1567 (Sizer, Teflon Seal)

NOTE: Use fuel injector O-ring seals that are made of special fuel-resistant material. The use of ordinary O-ring seals may cause the fuel system to leak. Do not reuse the O-ring seals.

NOTE: Do not lubricate the new lower Teflon® fuel injector seals.
