So i just recentlly got done putting in a new torque converter(that was fun) and have realized that when driving i have lost about 100 miles worth of driving to my full tank of gas. I used to get roughly 310 miles per tank now its barely getting over 200. Any ideas. Possibly time for a new fuel filter, that and my gas cap engine light keeps coming on didnt think that would really effect it since it was on before i changed my torque converter. I change the fluids regularly and kept up on all the basic maintance
