Some just sit in ruber boots, and are held in place by the hose it pumps out of . so yes they can be wiggled around.

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.

    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 tank on a 1994 4Runner, but need to know what other parts to get with it. Obviously the in-tank fuel pump, the fuel strainer, seals, but....is there a sending unit as well?


Hello, welcome to FixYa.

You would do well to purchase the cap/bracket assembly that holds the fuel outlet/return piping, it also holds the fuel pump and the fuel sending unit inside the tank. The chances of you re-using the original one are slim, as rust will have developed on the fuel pipes, and, if you bump them when removing the tank, they will crack. Also, get the bolts that holds the cap/bracket on, too. They do not cost that much. I'd replace the fuel sending unit and the strainer while you are changing the tank, also.

Thanks for choosing FixYa for assistance today!

1994 Volvo 960 engine cuts off at high speeds


It sounds like a fuel problem as opposed to an electrical fault. Start with the easiest fixes first ..
The next time the car comes to a grinding halt quickly remove the petrol filler cap and listen for air rushing into the tank. If you can hear air rushing into the tank that means a vacuum has been created inside it.

There are 2 causes of a vacuum inside the petrol tank. One is that the air-valve in the filler cap is blocked (there's usually holes in the filler cap covered by a rubber type ring) and the other is that the breather tube from the tank to atmosphere becomes blocked with dirt and debris thrown up by the roadwheels. Try driving the car with the fuel cap removed or very loose so that air can easily enter the tank. If the car still comes to a halt with the same symptoms, then there isn't a vacuum being caused within the tank.

A failing fuel pump can cause the same problems. I once owned a VW that had the symptoms you describe. The in-tank fuel pump was 'on its last legs' and when replaced the car was perfect.

A blocked fuel filter can also cause the same problems.

Here in the UK the Volvo 960 is either a straight-six 2.5 litre or 3 litre engine. I would guess that Volvos in North America share a pretty much the same mechanical layout depsite model differences. A UK 960 has two fuel pumps. One is located within the fuel tank and is accessed via an inspection plate behind the rear passenger seats (estate/station wagon models). The other fuel pump sits in a bracket underneath the car alongside the fuel filter, just aft of the front passenger seat (driver seat in the US..).

The in-tank fuel pump does most of the work, lifting the fuel out of the tank. The under-car pump lifts the fuel to the engine (it shares the same fuel line). Start with the easiest fixes first - is there a vaccuum in the tank that 'slows'/'holds back' the fuel? Then look at the fuel filter which is supposed to be changed every 40,000 miles.

If it's of any use to you, I've put some photos of the fuel pumps and fuel filter on my own website - www.glennsmart.btinternet.co.uk Just choose 'Volvo 960' from the drop-down menu.
