You might be talking about a fuel line, quick disconnect connection. If so the tool looks like a mushroom with one side cut out. There are a few different styles out there and you can pick it up any part store. Just ask for a fuel line quick disconnect tool. When you insert the tool it will spread the three metal tabs so the lines can be seperated.

We replace fuel filter but its leaking so can we replace just a section of the fuel line? And is this a hard job to do?


You can change a section using a pipe cutter (to cut out the section) and use "compression unions". Bring a piece of the fuel line to the automotive store and ask them for a piece of line and Compression unions. These unions just slip over the lines and tighten on them for a leak free fit.

How to change the fuel filter


Fuel Filter The filter should be inspected for external damage and/or leakage at least once a year. The fuel filter should be changed only as necessary. Toyota Motor Corporation recommends replacing the carbureted fuel filters at 15,000 miles and 30,000 miles on fuel injected models. NOTE: Fuel lines and connections, fuel tank vapor vent system hoses and fuel tank bands should be inspected every 60,000 miles or every 36 months. The fuel tank cap gasket should be replaced 60,000 miles or every 72 months.
---
REMOVAL & INSTALLATION Carbureted Engines The fuel filter on carbureted engines is a plastic cylinder with two ports for the fuel. It is usually located in the engine compartment near the charcoal canister.
  1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner. Grasp the clamps and slide them up the hose slightly above the filter ends 88271p10.jpg

  2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipe. Slide the hose off the end of the fuel filter end 88271p11.jpg

  3. Pull the filter from the clip and discard. Be carefull when removing the filter, some fuel may spill out if not held upright 88271p12.jpg
    To install:
  4. Install the new filter into the clip. The arrow must point towards the hose that runs to the carburetor.
  5. Push the hoses onto the filter pipes, then slide the clamps back into position.
  6. Start the engine and check for leaks.

Fuel line broke leading from fuel filter how can I fix it?


Measure the outside dimension of the line and head down to the auto parts store. If it is rusty where it broke you need to get a piece of fuel line with enough length to bypass the weak spot, usually 2 or 3 feet. Make sure they give you fuel line and not brake line. There is a difference in thickness. Also get 2 compression fittings the same size as the line and some emery cloth and a small tubing cutter.
Cut out the bad piece of line, on a straight section, and clean up the good ends with the emery cloth so the ferrules will slide on easily. Put the nut on first, then the ferrule and the the union. Withthe line butted snug in the union slide the ferrule in snug and tighten the nut. Don't overtighten, it's easy to wreck your joint. Do the same with the new piece of line. Start the car and check for leaks. Tighten nuts that need to be tightened if it's leaking, and you are done.
You shoul be able to do this for about $20-$30. Hope this helps.

How to change a fuel pump yourself tip?


The fuel supply and return lines are probably in bad shape, I'd recommend replacing them with the neoprene fuel line replacements, with the quick disconnect, first replace your fuel filter( it's located on the drivers side rear near the rear wheel looks like a canister in the line) again the quick disconnect lines can be used here, it will make your life easier later, these are available at most autopart stores along with the union pieces to run new lines, you can buy the quick disconnects for about $20.00 for 18 inches of new line with the quick disconnect clip on one end and the union pieces to put the line back together. Make sure the fuel tank is near empty, unhook fuel lines from the tank loosen the straps enouph so you can reach up and unplug the sending unit, now carefully loosen the straps( be careful with the straps they can be reused) until you can work the tank out, remember you need to be careful of the fill tube, if you damage it you will need to wrap it in rubber hose more unecessary work if you are careful. BEFORE YOU DROP THE TANK CHECK THE FUSEABLE LINKS, they are only a couple bucks, ALSO REPLACE THE FUEL FILTER 1ST. these items are cheap and could be the cause of your problem, the fuel pump runs about $100 but the work involved is dirty and not fun. Before proforming any repairs like this on your own make sure the vehicle is safely secured on jack stands, the rear has to be up quite a bit to give you room to work under the car. The fuel lines can be very time consuming, but will save you time when you are putting the tank back in after replacing the pump, and heaches down the road.

WHERE IS THE FUEL FILTER LOCATED ON A 1999 DODGE,CARAVAN?


The filter is tucked in over the fuel tank. Here's how I replaced mine... I put a jack (for a flat tire) under the fuel tank, so I could control how far it dropped. Then I removed the two screws that hold the fuel tank straps. The screws come out, the fuel tank is loose, lower the tank by lowering the jack. Now it is easy to reach the filter. One screw holds it in place. Unscrew it, it comes right out. The tricky part is figuring out how to unplug the fuel lines. Look at the replacement filter, note how the plastic piece inside each fuel line has to be squeezed to remove it. You need to squeeze the old ones the same way to release them. It isn't easy. Squeeze the plastic piece that is holding the hose in place until you can work it out. A few drops of gas will dribble out. The gas is NOT pressurized. Unsnap the old hoses, snap in the new ones (much easier). Screw the new filter into place. Jack the fuel tank back into place. Screw the straps back on. Clip the ground strap in place where the old one was. You're done.

Fuel leaking


If it's a 4.0 engine, the filter thing is the fuel pressure regulator (does it have a vacuum hose going to a fitting on the intake manifold?) Depending upon how much material (clean tubing) you have to work with the temporary"fix" is just about the same as the real repair. Cut the line, removing the failed part, and install a new piece of steel tubing, using crimp type unions (they have brass ferrules on both ends that seal permanently to tubing once they are tightened. Sometimes you need to remove a decent length to get to a straight clean area (unions are not recommended to be used on curved sections of tubing.
Or, if you can't do this, cut the tubing right over the leak, slip a piece of high pressure fuel line (rubber) over both ends and fasten with two clamps (made for fuel lines, not for water hose applications) Make sure that rubber hose extends at least one inch past the leaking area.That will get you to a shop! Check the regulator. it's doubtful that both the line and reg are leaking.
Good luck
