Fuel Line may Burst if Filter Screen Clogs

If the fuel line bursts, a significant amount of fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall, increasing the risk of a crash.

Summary

Cummins Inc. (Cummins) is recalling certain ISX15 diesel engines, part number D103012BX03, and X15 diesel engines, part number D103016BX03. These engines have nylon fuel lines and were built with a banjo bolt containing an integrated single screen filter on the fuel pump. The fuel pump cooling circuit screens may become restricted by debris from filtration material causing the fuel line to burst when the vehicle is operated under certain driving conditions, such as on a long down-hill grade.

Remedy

The remedy for this recall is still under development. The recall is expected to begin on October 9, 2018. Owners may contact Cummins customer service at 1-800-286-6467.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

*** IMPORTANT SAFETY RECALL ***
NHTSA Recall No. 18E-081

Dear Cummins OEM Customer:

We are writing to inform you that Cummins Inc. has determined that a safety-related defect exists in certain ISX15 and X15 engines that were manufactured between December 1, 2015 and July 24, 2018. Cummins has initiated a recall of the subject engines. Our records indicate that some of these engines have been shipped to you.

A copy of Cummins’ initial Part 573 Defect Notification report is enclosed. This notification was submitted to the National Highway Traffic Safety Administration (NHTSA) on August 10, 2018. As more fully described in the Defect Notification, if the fuel pump cooling circuit screens become sufficiently restricted and the engine is operated in an extended motoring condition, such as on a long down-hill grade, the engine may experience a burst nylon fuel line. If this occurs, the fuel line will leak fuel and the engine will not run when the operator depresses the accelerator. This condition may result in a significant volume of fuel leaking onto the roadway, causing a slick a road surface that may present a hazard to other motorists. This condition may also cause an engine stall without warning and without the ability to restart, presenting a risk of a crash.

Enclosed is a list of Engine Serial Numbers for affected engines that our records indicate were shipped to your plants. For engines installed in vehicles that have left your control, we encourage you to make a safety defect determination in accordance with 49 USC 30118 et seq. and, as appropriate, to submit a Defect Notification to NHTSA in accordance with 49 CFR Part 573. Cummins will conduct the recall, including notifying owners pursuant to 49 CFR Part 577, performing the remedy, and submitting quarterly status reports to NHTSA. Cummins is requesting that you provide the associated vehicle model identification, VINs and owner contact information to facilitate owner notification. Please work with your Cummins account team leader to ensure that the requested information is provided to Cummins as soon as possible.

For engines/vehicles that are still in your inventory, please contact the Customer Quality Assurance representative at the Jamestown Engine Plant to arrange for repairs. Please note that Federal law prohibits delivery of these engines, or vehicles equipped with these engines, under a sale or lease until this condition has been remedied.

Cummins is working to determine the field remedy and will communicate this as soon as it is available.
