PRODUCT DESCRIPTION
This DIY wiring kit includes the necessary parts to build a fuel pump power wiring harness. It uses the highest quality components to ensure proper operation in any condition. The relay and fuse holder are sealed to allow installation in weather-exposed areas, if necessary. The TXL aircraft-grade wiring is resistant to all types of chemicals and high temperatures. The Raychem crimp-less, solder-base butt connectors make for secure and clean wire connections. Also included are the necessary ring terminals for connection to an external Bosch 044 fuel pump.
