The Fleece FPE-FL-LB7-27 High Pressure Injection Line is a direct replacement for lines 2 and 7, built to solve one of the most common issues in the LB7 fuel system—corrosion. Over time, the original factory lines tend to rust internally, and when you're swapping injectors, that corrosion can break loose and send contaminants straight into your fresh set of injectors. It's a situation no one wants to deal with after spending time and money on an upgrade or repair. Precision Fit and Long-Term Durability Fleece designed this replacement line with reliability and fitment in mind. Each line is made from corrosion-resistant materials to ensure it holds up to the harsh conditions under the hood and the high pressures your fuel system demands. It's equipped with 4140 steel machined swivel nuts at both ends for a secure, leak-free connection. Installation is straightforward, thanks to its factory-style fit, and it directly replaces GM part number 97188723. Whether you're replacing worn parts or upgrading as part of regular maintenance, this high-pressure line gives you the confidence to know your fuel delivery is clean, consistent, and built to last.
