The CJM Return Correction allows DIY return system builders to maintain full functionality of the venturis in the fuel pump housing.
The factory in-tank regulator relieves into internal passages that lead to a pair of venturi jet pumps. When removing the in-tank regulator, you will require this product in order to continue feeding your return fuel into these venturis.
One venturi is used to promote canister refilling. The other venturi is used to draw fuel over the center of your saddle shape fuel tank (over the driveshaft).
Without this product in your fuel system build, your vehicle will be extra prone to fuel slosh starvation, and it will run out of fuel while the gauge is somewhere just below half tank.
This version is compatible with early G35 Sedan. Please provide your VIN number so that we can confirm your car has the correct fuel pump module for this.
