For most vehicles, including the Chevy Cruze, the most common cause of a gas tank not filling up is a clogged or saturated charcoal canister. The charcoal canister forms a part of the larger Evaporative Emissions Control System, EVAP, whose task is to collect and store fuel vapors from the fuel tank. However, this is not the only reason that may be inhibiting your gas tank.

Saturated EVAP Canisters
The EVAP charcoal canister in Chevy Cruze and other models is tasked with preventing harmful gas vapors from the vehicles’ tanks from finding their way to the environment. Usually, the canister is supposed to store the vapor until the engine utilizes them. However, the canister’s pores become less effective and efficient as time passes, leading to the gas filling to the brim. As a result, clogged or saturated canisters lead to slow tank refueling.
Possible Tools Needed
Basic saturated EVAP canister repair for a Chevy Cruze does not require special tools. However, you might still need a hydraulic jack, axle stands, square nose pliers, WD40, and Flexi hose clamp remover.
How to Fix a Saturated EVAP Canister for a Chevy Cruze
- Clean the area around the fuel tank cap.
- Locate the evaporative emissions control canister. Different model years may have the canister in different locations on your car; see below to find where your canister is located.
- Clean the hose connecting to the EVAP canister.
- Try filling your tank with gas.
- If the problem persists, replace the entire EVAP charcoal canister (you might need a professional for this).
Other Possible Reasons Why You Can’t Fill Your Gas Tank
Other causes for slow gas tank refueling include:
- Faulty check valve
- Faulty tank vapor or fueling valve
- Faulty gas station pump
- Dented filler tank neck
