- Mounting-flange seal: seals the joint where the throttle body or carburetor meets the intake manifold, helping block vacuum (unmetered air) leaks.
- Two names, one part: cataloged as both a carburetor flange gasket and a fuel injection throttle body mounting gasket, so it's listed under both names.
- Signs it may need replacing: a rough or unstable idle or a lean condition that traces to a leaking flange joint — if this gasket is the cause, replacing it restores the seal.

Frequently Asked Questions
What does the FJG103 gasket do?
It seals the mounting flange where the throttle body or carburetor bolts to the intake manifold, helping keep unmetered air from being drawn into the intake at that joint.
Is this a carburetor gasket or a throttle body gasket?
Both. It's cataloged as a carburetor flange gasket and a fuel injection throttle body mounting gasket, so it appears under both names for the listed applications.
What are signs this gasket may need replacing?
A rough or unstable idle or a lean condition caused by a leak at the flange joint. Diagnose the cause first; if this gasket is leaking, replacing it restores the seal.

It fits 25 Ford and Mercury applications from 1970 through 1991, including Mustang, Taurus, Escort, Econoline vans and F-Series trucks. Check the Buyer's Guide tab to confirm your exact vehicle.
