Got an ATL cell but didn't order the pre-installed fuel-level kit? No problem. ATL fuel-level kits can also be installed by you, after the fact, in all ATL cells offered through the LeMons store. Factory calibrated, they feature an enclosed, float-style sensing probe and come in fixed lengths keyed to the height of your cell. A lighted ATL fuel gauge (2.25" o.d., 1.875" i.d.) is also included. Choose the sensor length based on the depth of your cell, or ask an ATL engineer (800.526.5330) for assistance. Comes with a 20% restocking fee from ATL on returns.
