Replacement of fuel lines and pipeline connections (Taurus 1 and 2)

Warning: Before disconnecting the lines and hose ends, the fuel system pressure must be relieved (section 2). Gasoline is highly flammable, so special precautions must be taken when working with any components of the fuel system.

Threadless connectors - assembly and disassembly

1. Ford vehicles use two types of threadless line connectors. The 3/8" and 5/16" diameter lines use a fork-type connector, while the 1.4" diameter lines use a harpoon-type connector.

The assembly procedure for these connections is different. The clamps should be replaced each time they are disassembled.

2. Separate all pipes from system components: fuel filter, carburetor or injector, gas tank, etc. before removing the unit.

3. Inspect the connection - there may be dirt on it. Clean the connection before disassembling.

4. Over a long period of service, the pipeline may "grow together" - rotate the tubes relative to each other and move them in the axial direction.

5. Bend the latch tongue and, slightly spreading its legs, push them into the housing. Then, pulling the triangular protrusion, pull the latch out of the housing. Remember that this part of the work is done without any tools.



6. Pull the tubing out of the tip.



7. Do not reuse the retainer. Always replace with a new one.

8. Before installing the tip on the pipeline, wipe the end of the pipeline with a clean cloth. Check for dirt.

9. When connecting the tip to the pipeline, align them and push one into the other. Then install the retainer by inserting its legs into the holes in the tip body and pressing the triangular protrusion with your finger until the tongues lock it. The top of the triangular protrusion should be directed away from the pipeline.

1/4" diameter connectors (with harpoon latch)

10. The connector with a harpoon lock consists of a body, intermediate rings, a seal and a lock (see figure).



The retainer holds the tubing securely inside the tip. To disconnect the connector, use one of the two methods described below.



11. Before starting work, check whether dirt has accumulated in the visible inner part of the tip. The tip should be cleaned before disassembling

12. After a certain time, the tip and the pipeline "stick together". Turn the tip in the pipe, then move it along the axis until it moves freely.

13. The preferred method of disconnection requires the use of a special tool. Align the groove of the special tool for assembly and disassembly (Ford parts NT82L -9500 - AN or similar) with the corresponding protrusion of the retainer (located at an angle of 90 degrees to the grooves on the side of the retainer), and insert the tool (see figure). This will disconnect the connector and the pipeline.

Note: Some fuel lines have a secondary lip that aligns with the outside surface of the connector. This may prevent the tool from being inserted. In this case, use the alternative disassembly method described in step 16.

14. Holding the tool and the pipeline with one hand, remove the tip (see figure).

Note: Moderate force is sufficient if the clamp is properly released. It is recommended to use only your hands.

15. After disassembling, check and clean the sealing surfaces of the pipeline. Inspect the inner surfaces of the pipe and tip - foreign parts from the connector may have gotten there. Deformed parts should be replaced.

16. The alternative disassembly procedure requires Chanelok pliers. The working part should be no more than 3/16 inch wide.

17. Place the jaws of the pliers on the holes on the side of the tip and squeeze the retainer that secures the body. The retainer will separate from the body (it is necessary that both parts of the retainer separate at the same time).

18. Remove the tubing from the tip.

Note: If the clamp has been disconnected correctly, moderate force will be required. Do not use auxiliary tools.

19. After removing the connector from the pipeline, check whether any parts have fallen inside the pipe or tip. Lost parts should be replaced.

20. The retainer must remain on the pipeline. To remove it, it must be released from the flange of the pipeline. Do not install a used retainer - only a new one.

21. Before installing the connector, clean the pipeline with a clean cloth. Check the inner surface of the connector - make sure there is no dirt or foreign objects.

22. When installing the tip, align it with the pipe and push it into place. You will hear a characteristic click when installing. Pull the tip to make sure it is firmly in place.

23. Insert one of the serrated ends of the duckbill into the hole and install the new clip. At the same time, pull on the other side until the clip snaps into place.

Spring-lock pipeline connectors - assembly and disassembly

24. On some engines with CFI and EFI systems, the fuel supply and return lines use spring-lock connections instead of plastic "push" ends of hoses and pipes. The male end of the spring-lock connection, encircled by two O-rings, is inserted into the female end of the tube with flanges extending from the engine. The reliability of the connection is increased by a Garter spring, which prevents one end from slipping out of the other (see figure).





25. The diameters of the connectors of the supply and return pipelines are different. To disconnect a 1/2 inch connector of the supply line, you will need a spring-lock tool D87L - 9280 - B or similar, for a 3/8 inch outlet connector you will need D87L - 9280 - A or similar.

Split connection

26. Before disconnecting the tips that enter the spring lock, release the pressure in the system (see section 2).

27. Disconnect the negative battery cable.

28. Using a small screwdriver, lift up the safety catch on each tip (see illustration).



29. Install the separation tool in place, selecting it approximately according to size (see figure).



30. Close the tool body, push it into the open part of the ferrule to release the Garter spring and release the enclosing tube (see figure).

Note: The spring may not release if you tap the tool while pushing it into the clip slot.

31. When the spring is released, pull the tips out of each other.

32. Remove the tool.

Assembling the connection

33. Make sure that the Garter spring is in the male end sleeve. If it is missing, insert a new one into the sleeve slot. If damaged, pull it out of the sleeve using a small hook (do not use a screwdriver) and install a new spring (see Fig. 3.24 for spring sizes).

34. Clean both parts to be connected from dirt and foreign objects.

Warning: Use only standardized O-rings, they are made of special material, installing non-standard rings may cause leaks.

35. Lubricate the male end, O-rings and the inside surface of the female end with clean engine oil.

36. If the assembly includes a plastic indicator ring, place it into the socket of the clip.

37. Insert the female and male tips into each other and push until the Garter spring compresses the female tube flange.

Note: if there is a plastic indicator ring, it will be pressed away from the connector of the clamp, thus indicating the moment of assembly of the connection. If there is no indicator ring, you should visually check that the Garter spring has compressed the flange of the female tip (see figure).

a) before disassembling the connection, put the white indicator ring back in place, as it could have slipped along the pipe.



b) after disconnecting the tips, insert the white indicator ring into the female tip collar.

v) later, during assembly, the white indicator ring will flap freely on the collar of the male tip until the connection is fully assembled.
