QuadrajetParts.com 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 QuadrajetParts.com. All Heli-Coil thread inserts are machined on our milling machine. QuadrajetParts.com 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.
After ordering a QuadrajetParts.com service. Ensure that ALL gasoline is drained and evaporated from casting. Wrap up your carburetor main body with lots of packing material to protect the fragile casting. Ship your Rochester Quadrajet Carburetor main body and a copy of your online order receipt to:
36 Mount Pleasant Road
Columbia, NJ 07832
Please note that not all main bodies can be repaired and we cannot guarantee a successful installation as some main body inlet threads are just too damaged to allow a successful repair.
NOTE: Send only your bare main body casting (Remove base plate, air horn and all internal components).
Complete carburetors sent will be charged an additional $20.00 for disassembly. If you request the carburetor to be re-assembled, there will be an additional $30.00 charge. Note re-assembly does not mean rebuilding or adjusting float levels ect. Complete carburetors (due to the increased weight) will be charged an additional shipping surcharge to cover added shipping expense.
