SOURCE: the transmission cooler line on the bottom that

As far as I know, that clip is not replaceable... (called a quick disconnect).
The entire tube assembly may be, and likely can be done by any decent radiator shop. Assuming the end part that broke is the radiator end. Otherwise, you will need to get a replacement line either from a dealer or from a scrapyard. There may be several "jury rig" options you could use to make a repair, but I don't recommend doing that there because of the location.(tight and difficult to reach) Jury rig is fine for stuck in the woods situations...do it right if you're home.

You have to check for spark and fuel pressure. The 3800 motor can have a bad module (sits right below the coil pack, as well as bad coils. Also check for fuel pressure. I put a brand new dealer pump in a 93 Olds once and it was not putting out enough pressure to engage the injectors. Section 4 in a Hayes manual found at most Advance and Auto zone stores will give you the fuel pressure reading you need.

Hope this helps.

Test the fuel pressure. Should be 60 psi I believe. Remove gas cap and listen for sucking sound. Should not be any. If there is, then purge valve bad.

Leaking fuel pump


If the fuel is leaking into the car you will need the replace the seal on the top on the pump assembly not the seals on the pump itself but before changing the seal just double check the fuel lines are tight and the leak is actually from the fuel splashing out of the tank. The seal your after is referred to as the pump assembly oring ( big rubber oring around the top of the assembly a smear of silcone can be used as a temporary fix but erge you to get it fix properly as soon as possible and fuel fumes in the cabin can be extremely deadly)
Hope this helps

How to change a fuel pump on a 1992 Toyota carolla


Electric Fuel Pump-Fuel Injected REMOVAL & INSTALLATION The electric fuel pump is contained within the fuel tank. On 1988-92 models, it is necessary to remove the fuel tank from the vehicle in order to reach the pump. On 1993-97 models, the fuel pump can be accessed by removing the rear seat cushion and service hole cover. 1988-92 Models Fig. 1: Exploded view of the electric fuel pump 88275g77.gif
NOTE: Before disconnecting fuel system lines, clean the fittings with a spray-type engine cleaner. Follow the instructions on the cleaner. Do not soak fuel system parts in liquid cleaning solvent. CAUTION
The fuel injection system is under pressure. Release pressure slowly and contain spillage. Observe "no smoking/no open flame'' precautions. Have a Class B-C (dry powder) fire extinguisher within arm's reach at all times.
  1. Disconnect the negative battery cable and relieve the fuel pressure. Remove the filler cap.
  2. Remove the fuel tank from the vehicle.
  3. Remove the fuel pump bracket attaching screws, then remove the fuel pump/bracket assembly from the tank. Fig. 2: Remove the bolts retaining the pump bracket to the fuel tank 88275g78.gif

  4. Pull the lower side of the fuel pump from the bracket.
  5. Remove the nuts attaching the wires to the fuel pump.
  6. Disconnect the hose from the pump.
  7. Separate the filter from the pump. Use a small screwdriver to remove the attaching clip. Fig. 3: Pull off the lower portion of the pump from the bracket 88275g79.gif
    Fig. 4: If necessary, remove the clip and pull out the filter to replace it 88275g80.gif

  8. While the tank is out and disassembled, inspect it for any signs of rust, leakage or metal damage. If any problem is found, replace the tank.
  9. Inspect all of the lines, hoses and fittings for any sign of corrosion, wear or damage to the surfaces. Check the pump outlet hose and the filter for restrictions.
  10. When reassembling, ALWAYS replace the sealing gaskets with new ones. Also replace any rubber parts showing any sign of deterioration. To install:
  11. Install the pump filter using a new clip. Install the rubber cushion under the filter.
  12. Connect the outlet hose to the pump, then attach the pump to the bracket.
  13. Connect the wires to the fuel pump with the nuts.
  14. Install the fuel pump and bracket assembly onto the tank. Use new gaskets.
  15. Install the fuel tank.
  16. Start the engine and check carefully for any sign of leakage around the tank and lines. Road test the vehicle for proper operation.
1993-97 Models CAUTION
The fuel injection system is under pressure. Release pressure slowly and contain spillage. Observe no smoking/no open flame precautions. Have a Class B-C (dry powder) fire extinguisher within arm's reach at all times. Fig. 5: Exploded view of the fuel pump components 88275g81.gif
  1. Disconnect the negative battery cable. CAUTION
    On models with an airbag, wait at least 90 seconds from the time that the ignition switch is turned to the LOCK position and the battery is disconnected before performing any further work. Refer to Section 7 for all air bag warnings.
  2. Relieve the fuel pressure.

Need to replace the fuel pump


Start with an almost empty fuel tank. a BIG help! 
Tools needed: Regular pliers. needle nose pliers or a pick type tool for retaining ring around the fuel pump. Floor Jack (heavy duty) size 15 metric socket, extension, and ratchet (or air ratchet) Flat head (standard) screw driver to disconnect the hoses from the fill tubes. ( where the gas station person fills up the tank). Fuel line Disconnect tool set (two little Plastic parts to remove fuel lines from pump) a MUST need item. Cant remove with out them. Napa part number BK.700-1932 around $10.
Then you will need a partner or helper. With the vehicle on level ground, (not on ramps) and the park brake set, make sure you take the keys OUT of the ignition. You will need a metric size 15 socket for the two (2) bolts that hold the straps under the fuel tank. Put the Floor jack under the Center of the tank. lift jack until snug against the bottom of the tank. Remove the two bolts (one per strap) holding the tank straps up. Move straps to the side out of the way.
Loosen the hose clamps on the fuel hoses coming from filler tube. Carefully pry hoses off from metal tubes. Slowly lay to the side of the tank, and have the HELPER lower the jack very SLOWLY. The tank has been up there for awhile, so it might need to be coaxed away from the body of the truck. Lower the tank a little bit at a time until you can see the top of the tank.

You might have to Squeeze yourself up in tight against the tank to see it. The reason I say very slowly is that the fuel lines are not long enough to lower the tank all the way to the ground. Once you can see the top of the fuel pump, you will have two electrical connectors to disconnect. 

Be very careful, they have clips on the side of one, and on top of the other. Then you can again, squeeze yourself to where you can get both arms up to assist in using the two plastic fuel line disconnect pieces. Two different colors, one is bigger than the other. Slide one tool onto one of the hoses going into the fuel pump. (You'll understand once your under the truck and looking at the top of the fuel pump).

Then carefully remove each hose. After removing the hoses from the fuel pump, you will need a pair of pliers to remove the clip (Or just slide the clip back) from a vent hose. Now ALL hoses and connections should be disconnected. Now you can lower the tank all the way down and slide it off of the jack and pull the tank out from under the truck.

Take the needle nose pliers or punch, and remove the retaining ring from the top of the fuel pump. You can now pull the fuel pump out. You May need to pry up on the pump to get it out. Put your new pump in, making sure that it is in correctly. there is a little notch that you need to look at the old pump before removing it. You'll see it. Now just reverse all the steps to putting it all back together. 

Good luck and hope this helps, oh and it's a good thing to replace the Fuel Pump wire harness from the frame to the gas tank. I believe there like $15.00 last i bought one, may have gone up.

Fuel Pump


it is not necessary to drop the tank. In the boot, on the left, you can see a cover towards the back seat. The carpet cover need to be removed first. Unscrew the four nuts and you can see the all the hoses connected. You need the special tool to unscrew the black plastic cap. The pump is attached to the floater. Ensure that before fixing to check the plastic head at the vacuum return head is not crack and replacement is needed for new rubber seal on tightening the black plastic cap. After all done, check on possible fumes leakage.
