## NHTSA's summary

Fuel Tank Issue Description: Ram 1500 built between 7/1/16 and 8/15/16 with concern of "hard to fill" or "premature shut off", please remove the Canister line and Recirculation Line and retest. If the condition continues, tank replacement may be required. Please reference the proper diagnostic materials. Answers to the following questions can assist Engineering in their quality improvements: 1\) At what level of fuel in the Tank does the Hard to Fill condition exist? 2\) When did the customer start experiencing Hard to Fill condition? 3\) Did the condition exist in a particular fuel station? If tank replacement is needed, please contact Sylvia Lopez at Cell \(248\) 520\-9734 prior to replacing the Tank. She will help arrange shipment of the tank back to the Quality Engineering Center. If no response within 15 minutes proceed with repairs
