Service- Fuel Inlet Thread Repair, Heli-Coil Installation, 1\" Inlet Carburetors will install a Heli-Coil Thread Insert on your Rochester Quadrajet Carburetor with 1" diameter fuel inlet. This will restore your stripped out inlet threads, allowing the use of your original inlet fitting. The absolute best solution to stripped or worn carburetor inlet threads.

Quadrajet carburetor note:
1" inlet fittings are found on all 1972 and later automobile and truck Quadrajet carburetors.

We do not tap inlet threads by hand at All Heli-Coil thread inserts are machined on our milling machine. has built a dedicated Quadrajet mounting fixture on our DRO milling machine to insure the installed inlet threads are concentric to the sealing gasket surface. The installation process for the larger 1" inlet threads is more labor intensive and requires custom tooling, but the result will allow the original style inlet fitting and seal to properly work. After installation, every thread insert repair is pressure checked to verify a leak free installation.

Normal turnaround time is 2-3 days.

If you require any packages to be insured for more than the invoiced charge amount, please contact us and request that additional insurance be purchased for your package.
