The Diesel Defender is designed as a one-piece unit with 4mm thick aluminum side walls which allows for hands-free filling with no splashback! It was tested on high flow pumps filling up to 50 gallons per minute. The Diesel Defender is easy to install and requires no drilling, riveting or maintenance once installed.
