The Low Profile Fuel Line Disconnect, No. 39120 from Lisle Corporation features a flexible one-piece design that, according to Lisle, is meant to work better than two-piece disconnect tools. The double-ended tool is designed to fit into the limited clearance between the fuel line and high-pressure fuel pump. Made from durable, flexible acetate, this tool works on 5/16" and 3/8" fuel lines found in 2010 and newer Ford vehicles with 1.6L, 2.0L, and 3.5L GTDI, as well as 6.2L Boss engines.
