FAQ
Will this kit fit non-intercooled 1989–1991 trucks?No. Those applications commonly use 9 mm injector nozzles; this kit is for 7 mm nozzles found on intercooled models.
How do I confirm 7 mm vs 9 mm injectors?
Check injector part numbers or measure nozzle diameter. If uncertain, provide your VIN/ESN and we can help verify compatibility.
Is the kit sized for all six injectors?
Yes—this install/seal kit is intended for the six-cylinder 5.9L platform when performing a full injector reseal.
Do I need additional parts?
Inspect injector hold-down hardware and fuel lines; replace as needed. Consider fresh return line washers and line clamps if worn.
