How do I remove my fuel pressure regulator from my fuel pump assembly on a 99 Toyota Corolla

Hello, not sure if I understand, the pumps are available at almost all auto parts stores for around $30, that's the pump only and you will have to remove the old pump from the assembly in the tank, fuel pressure should be about 45 PSI regulated.

It 's part of your fuel pump assembly.(inside gas tank)

It sounds like the fuel pump is going bad. If you had a fuel pressure tester you could check dead head pressure with the vehicle off and in the run position. A good operating pressure is about 41psi estimation. If you see the pressure drop right away and does not hold the pressure then the check ball or fuel pressure regulator is bad and you need to check those. Im giving proper diagonis procedures before buying somethimg you dont need. You can check a fuel pressure regulator with applying a vacuum to the valve and if the valve diaphragm holds pressure then it is good. Then all you have left is a bad checkball inside the fuel pump assembly. Unfortunately, if the ball valve is bad the whole fuelpump needs replaced. If you replace the assembly replace the filters too. A good tip to save the life of fuelpumps is to never allow the tank to run below a quarter tank because the fuel acts as a cooling system for the pump.

Replacing fuel pressure regulator on Toyota Vitz, Yaris and Eco:
1. Remove rear seat.
2. Remove rear service hole cover.
3. Remove fuel pump and vapor pressure connector.
4. Start the engine till it stops on it own and switch the ignition to OFF.
5. Remove the tube joint clip, wrap a piece of cloth around it and pull out the main tube.
6. Pinch the fuel emission tube connector clip and pull it out.
7. Remove the 8 bolts and fuel tank vent tube set plate.
8. Remove the fuel pump assembly.
9. Remove the O ring from fuel pump assembly.
10. With help of screw driver remove the fuel pump locking plate.
11. Remove the fuel pump regulator with screw driver a bit force fully.
12. Assemble the fuel pump assembly in the reverse sequence of dis assembly.



Hope that it works. Thank you for visiting Fixya.

searching why, (buy an FSM and no more guessing...? )
basic service?
low fuel pressure? why?

ive got near a 1/2 million + miles on jeeps since 1988.
never stranded, but i do my service,.
my last chick-o-dee. was 99. with 5sp, all with that.
my 08 JK same.
the fuel filters on old loop systems is in the front of the tank
then later, , EPA forced most parts into tank with the new loop
or dead head systems. (EPA wants fuel cold .so, that is it)
i dont find parts hard to find, jeeps excel at that. vast resources.
nor hard electrical if you had a 2007+ then that be different.

id just crawl under car and gander, at fuel line but here we go
ill do it , online for you.
4Liter 98
options , with the 20gallon tank there is filter. on top of pump , in tank.
that means to me there are different filters there. by size tank .
if you dont see a filter, that means its in the tank.

so

ill paste the FSM page on this topic

he fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.

1. Disconnect the battery ground cable.
2. Relieve the fuel system pressure. Refer to Section 5 for the proper procedure.
3. Remove the fuel tank assembly.
4. Clean the area around the fuel filter/regulator.
5. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
6. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
7. Remove and discard the mounting gasket below the filter/regulator.
8. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.
9. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
10. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
11. Apply a small amount of clean engine oil to the O-rings.
12. Install a new gasket on top of the fuel pump module.
13. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
14. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O'clock position).
15. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O'clock position.
16. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
17. Install the fuel tank assembly.
18. Connect the negative battery cable.
19. end

how is that ?

LOOK ON THE FUEL INJECTORS RAIL YOU SHOULD SEE A BLACK CAP THAT LOOK LIKE A TIRE AIR PRESSURE STEM REMOVE THE CAP AND FUEL PRESSURE REGULATOR IS THERE

whats your fuel pressure? you can be running low fuel pressure and the pump could be going also id check pressure regulator take your vacume gun apply vacume to it while its running if engine dies pressure regulator is good

Yes it does have an o-ring. Below is a break down diagram of your fuel pump componants were the fuel regulator is. As you can see it does require an o-ring. Hope this helps......

The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank.

1. Disconnect the battery ground cable.
2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
   
3. Remove the fuel tank assembly.
4. Clean the area around the fuel filter/regulator.

1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.

To install:

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
3. Apply a small amount of clean engine oil to the O-rings.
4. Install a new gasket on top of the fuel pump module.
5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
9. Install the fuel tank assembly.
10. Connect the negative battery cable.

remove the bottom of rear seat. open the service door on rear floor. take out the bolts that hold fuel tank set plate to the fuel tank, then now you can remove fuel pump assembly.
