Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injector seal kit may be the cause:

• Fuel leak at injector base — Copper washers lose their crush seal over time. If you see dampness around the injector, the seals need replacement.
• Fuel in coolant or oil — A failed combustion seal allows fuel pressure to escape into adjacent passages. This is a serious issue that requires immediate attention.
• Loss of compression on one cylinder — When the copper sealing washer fails, combustion gases blow past the injector body instead of pushing the piston.

Installation Notes

Clean the injector bore thoroughly before installing new seals. Any carbon or debris left in the bore prevents the copper washer from seating properly, causing a compression leak. Use a wire brush or bore cleaning tool, then wipe with a lint-free cloth. Install the seals in the order specified in the kit — the heat shield goes on first, then the copper washer, then the O-rings. Torque the injector to the specified value and recheck after running the engine under load.

Frequently Asked Questions

Can I cross-reference FJ394 with MD116821?
Yes. Both FJ394 and MD116821 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.

How do I check if my engine code (FJ394) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long.

My vehicle is a 1991 model – is it covered?
The compatibility range for this part includes 1991-1994. The 1991 model year falls within this range, but verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.
