Section 5A Fuel Lines
5A-2. Disconnect the other end of the fuel supply line from the steel line. This connection is
located between the frame bracket and the front of the fuel tank as shown in fig 15 on the
previous page. You may now remove the 18” of factory flex line.
5A-3. Insert the female Quick Connect end (see figure 15) of the “Pressure Hose Assembly”
into the male quick connect fitting previously installed in the port marked “ENGINE”.
You will hear a “click” when properly connected.
Figure 15
5A-4. Route the female end of the “Pressure Hose Assembly” along the frame towards the
engine. The hose is 7’ long so be sure to give enough clearance to route hose without
causing a restriction.
5A-5. Using the fuel line disconnect tool, disconnect the larger of the two lines where they
connect to the engine on the driver side under the brake booster. If you are having trouble
finding the connection follow the lines up from under the truck to where they end as
shown in the pictures below.
5A-6. Once the stock line is disconnected, connect the female end of ½” hose supplied in the
kit, to the male end that was unhooked from the factory line, a “click” will be heard once
fitting is securely locked. Tie factory line out of the way once complete.
Any excess fuel hose can be addressed by removing a section using the supplied hose
splices in the kit. Hose clamps are not required when using these splices.
