The CJM Return Correction allows DIY return system builders to maintain full functionality of the venturis in the fuel pump module.
The factory in-tank regulator relieves into internal passages that lead to a pair of venturis. When removing the in-tank regulator, you will require this product in order to continue feeding your return fuel into these venturis. One of these venturis creates a swirl function which reduces aeration and promotes canister refilling. The other venturi is a jet-pump used to draw fuel over the center of your saddle-type gas tank (over the driveshaft). Without this product in your fuel system build, your vehicle will run out of fuel while the gauge is somewhere just below half tank.
This version is compatible with all 350z, and with G35 coupes (not sedan).
