The larger diameter neck out of the fuel pump is the pressure output and goes to the line that goes to the fuel filter. The other one is the low pressure return line, which is fuel returning to the fuel tank from the fuel injector rail. This question is making wonder, because the quick connect fittings on the end of the lines, are different sizes, and can't be crossed up. I am sincerely hoping that the OEM lines are still present, and we are not trying to clamp bulk rubber lines onto the system. Because clamping rubber lines in place of the OEM lines, is asking for a serious explosion.
Take a good look at the hoses and fittings. They are three different sizes. They can only fit correctly one way.
there are not a lot of hoses, you have one from the fuel pump under the tank to the carb and one from the fuel pump to the intake for vacuum, there is also one from the air box to the valve cover for ventilation. the bottom of the fuel pump is what connects to the carb, the side is for vacuum.
You need to drop the fuel tank. Also you need to remove the hoses that go from the fill port to the tank.
The fuel pump is in the gas tank. You have empty the gas tank, disconnect the hoses and holdup straps and then lower the tank. The fuel pump/gas gauge module are screwed into the top of the tank. Go to the library and take out the repair manual.
go to the back seat and pull the two tabs in between the seat and the floor and pull the seat up and out. And you will see the fuel pump, remove all hoses and bolts and it comes out, dont be surprised if you spill a little fuel.
There is no magic potion that will rejuvenate a tired electric fuel pump. A new fuel pump and fuel filter is the best way to go.
Thers a filter mesh on the in tank fuel pump , which you get to under the rear seat. thers a filter on the hoses that go to the injection rail near the fuse box in the engine compartment. My problem was that the fuel pump was knakered and replacing it sorted my fuel problems
first....you buy a new or used fuel pump.....i recommend buying a used one because a fuel pump for a 1999firebird will cost you about 200$ or more.......there are two ways that you can replace the fuel pump......one way is to get the car on a lift and drop the fuel tank from under the body..... then the fuel pump will be easily accessible....take there will be two wire connections and three fuel hoses coming off of the pump.........take those off then get a hammer and chisel and GENTLY knock on the chisel where the locking plate is locking the fuel pump to the tank...... then put the new or used pump in....then you want to connect the hoses back together.......then put the fuel tank back up in to the body and then put the supports back in place the second way of doing it is a little low tech......... you take the carpet out from the trunk then get an angle grinder then cut a hole in the trunk in the hump......then take the fuel pump out like i said in the above method and then put in the pump with the above method....... get some silicone caulk to seal back the hole that you cut....then you are ready to go I have done it 2 times...... once in the middle of nowhere.....
Take out passenger seat, go into the glove box behind.Pull out the bottom. Disconnect the fuel hoses from the pump assembly. Take out the screws holding the pump assembly in place and pull out the white housing. Then use a fluid transfer pump to remove the fuel
no reset common for them to go bad.
Inside the gas tank. In order to get at it, you have to disconnect the gas tank, and youll find where three hoses go in, a screw-type ring. back off the ring, and theres your fuel pump.
