Just find the lines leading from your wheel to where you need to cut them.

is the ABS light on? Check the crank sensor wiring down the back of the block, it may have melted on the exhaust. It runs in between the firewall and the engine, 2 wires.

My brake line on my 97 tarus blew out under my driver door in a "little back box" thing. How do i take it off the frame of my car to replace a part of the line..

You will need to take a look at the line from front to rear, this job can get big fast, and if you have ABS (anti locking brakes ) it makes it harder, if you can see a good part of the line where it can be cut and flared with an end then cut it there, the black box is just a plastic cover. that cover holds the dirt and water and makes the lines rust sooner, i do these lines all the time and most of the time i run new lines from front to the rear brake hose , most of the time if there is another weak spot then you will be doing the job again and again.

you will need brake line a flaring tool, a bubble or double flaring tool to make the line ends and fittings and connectors, you will need to bend the line by hand and when your done you will need to bleed the brake system.

My 99 surburban 1500 is leaking radiator fluid from the middle of the truck underneath.not from the radiator itself but from one of the 2 lines that run from the radiator down to the middle somewhere, its...

Sounds like the rear heater lines are leaking. You can cut them and replace them with rubber hose or by-pass it by just blocking them both off. The call is going to be made when you get on your back and slide under it to evaluate the condition of the rest of the line(s). Heater hose is what they use all the way back on conversion vans so don't be afraid of using a little hose if you need the rear heat next winter. st Just make sure you fasten it to the frame well so the snow and ice dont pull them down and brake them. (If you live in the snow belt like me)
Good Luck and God Bless

I just replaced fuel pump on my 99 pontiac grand

Anytime when there is multiple issues, I pick one system when the problem is ongoing, check voltage and ground.
The fuses in picture is for instrument cluster, Check for voltage at the fuses when problem is ongoing. Use a test lite. As you can see, one fuse is hot all the time, the other goes hot with the key on.

I have a broken brake line above my gas tank and I can not find a diagram to show me if the line runs straight across the tank or if there are other connecting lines above the gas tank that I can not see....

Look at the differential housing and you'll find a "T" with a flexible line going to that broken line above the tank. Cut and connect another a replacement line from front of tank around to the "T" and then bleed the rear brakes. The single line feeds both rear brakes from that "T" and there are no other lines connected to it. Done this way will keep you from having to drop the fuel tank to get to the line to replace it.

po171 is a lean code, and could be likely caused by a plugged fuel filter, or a weak fuel pump, I would recommend changing the fuel filter first since its cheaper.. The filter is located under the rear of the vehicle by the fuel tank, if this doesn't help run, or have run a fuel pressure check to determine if that is the cause. Also look carefully under the hood for any hoses or lines disconnected causing a vacuum leak, this can also cause a lean code

My 99 grand am is idling fast and slipping?

i think you have an air leak with this new gasket you fitted that would make the engine run faster as its running very week and drwing secondery air , witch is why you have low presher,, the thumping you get when you put the car in gear is becouse its ticking over too fast it could brake a drive shaft if you dont sort the manyfold gasket out soon, check all the bolts around the intake are tight first, but my gess is its leaking badly

check all fuses for turn signal and brake lights.change fuel filter . first. do a little tune up change spark plugs and wires . if changing fuel filter dont help. have fuel pressure check first before buying a new fuel pump .they run after taxes 400.00 dollars. your fuel pressure should be 41 to 47 psi. replace fuel pump relay also.
