2008 Chevrolet Corvette Fuel Filler Hose

General Motors (GM) Upper Engine and Fuel Injector Cleaner is the only injector cleaning agent recommended. Under no circumstances should the GM upper engine and fuel injector cleaner be added to the vehicle fuel tank. You should not exceed the recommended cleaning solution concentration.

You should remove the right rear wheelhouse panel, remove the evaporative emission (EVAP) canister access cover, disconnect the Fuel Tank Pressure Sensor electrical connector and then remove the fuel tank pressure sensor by carefully prying the sensor out of the fuel tank with a screwdriver.

You should insert the new level sender assembly into the slot, slide down until the lock tab engages, route wires next to the regulator ground wire and up to the electrical connector, slide the level sender wires into the open slots in the electrical connector, connect the electrical connector into the flange, test the level sender resistance with an ohmmeter, install the module into the tank, measure the resistance across the level sender with tank upright, roll the tank over and then return the tank to the upright position.
