Official summary
Dealer Letter: March 23, 2018 Parts Ordering section has been updated. Toyota will initiate a Special Service Campaign (SSC) to replace the fuel pulsation damper on certain 2003 Model Year (MY) Toyota 4Runner V6 vehicles. On certain early 2003 Model Year 4Runner V6 vehicles, the fuel pulsation damper, located on the fuel rail, may have been improperly assembled. If the pulsation damper fails, a small amount of fuel may leak. In the worst case, this may result in an engine compartment fire if a heat or ignition source is present.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
