SOURCE: fuel line replacement 96 LeSabre

My computer just hosed my response so forgive the clutter if half of it posts.

The answer to our problem is GM and AC part # 25625186. It costs $62.10 plus tax but I didn't have the patience to wait & see if the 20 dollar part (no picture - not in stock) from local parts store was correct.

LEAVE KEY OFF to release pressure from fuel line. It is always a good idea to disconnect the battery while working on a car. The hose diconnects on either end by pushing the two tabs on the clear/white fastener hooked to the filter on one side and the hard line on top. Small hands and a screwdriver or pliers may help but the job can be done with (thin gloved) fingers. I take that back... I needed a screwdriver to open the rubber bracket on the frame and help pry the top hose out. Next make sure the clear/white insert fasteners are included with the new part so you can go ahead and rip off the pieces left on the hard lines. Make sure there is no dirt on the hard lines and firmly press the new part in place. There should be a nice SNAP when it is connected on each side. This was an easy one besides the fuel mess and hit to the wallet. Please wear safety glasses and take precautions for dripping fuel and dirty undercarriage.

SOURCE: I have a 87 volvo that i need to replace the fuel

I'll tell you. In the trunk, behind the rear seats is a raised deck covered in carpeting. underneath, there is a galvanized steel plate, with 4 screws holding it down. underneath is th fuel pump cover, 3 wires, 2 hoses. to remove it safely, go to and order the fuel pump bung nut tool. After that, the fuel pump, sock, and sender unit can all be lifted out (it is all one assembly). Have fun!

What is the canister?

"Canister" usually refers to the charcoal canister. It's part of an emissions system called the evap system. It's a canister that contains a refined form of charcoal that absorbs evaporated gasoline from the fuel tank, and stores it until the computer opens a valve and it is burned by the engine.

I have a po442 code on a 2007 Chevy Tahoe

p0422 is a small leak in what is called your EVAP system basicly its the pressure that is held inside the fuel tank its an emissions thing there two valves one by the tank called the canaster vent solenoid and one on the intake manifold called the canaster purge solenoid . The vent sends fume from the tank to the charcoal canaster when the pressure is high inside the tank and is stored until the engine speed is high enough to open the purge valve to allow this vapor to be burned in the engine It could be anywhere in the system a leak but the gas cap often be the problem if its not sealing ther you will have a small leak in this system . It could be something else but see if when you remove the cap after driveing for a while if you have pressure when you remove the cap it is likely the problem

My 1998 gmc envoy code #P0453 has been a problem as well for me forgot to mention earlier on last question. any help, thanks

Are you the guy who had P0302 code.P0453 is the fuel tank pressure sensor is reading to much pressure to high that would explane why it would pass emissions Iwould check a part called the canaster vent soleniodif its stuck or cloged you would have a high pressure level in the tank it sends fuel vaper to the charcoal canaster from the tank where it is stored until your at highway speed then the canaster purge sloeniod opens and the vaper is burned in the engine. Ihave a 96 blazer and had a simaler problem but i was getting P0304 # 4 cylinder misfire although i had to replace the fuel pump to but that was part of the problem.You need to remove the spare tire and its on the top of the frame cross member above the tire mount check the filter thats in it and you can check to see if it works by jumping 12 volts across it it should click you will feel it move if its good. Ican't say for sure but i can't see the vehicle and this makes a lot of sence to check first and likely will clear up the problem it cost about 30 dollars for a new one

What is a p0442 code for my 2006 Suzuki Forenza?

P0442 means that there is a small leak in what is called the evap system What it dose is take gas fumes from the fuel tank and divert them to the charcoal canaster to be burned in the combustition system routed through two solinoid valves called the canaster vent valve and the canaster purge valve the vent being from the tankto the canaster and the purge being canaster to the combustion chamber Its a small leak it could be anyware in the system but i would replace the gas cap first many times it starts to leak at the seal and will set this code Its all for emissions and dosn;t have a large effict on over all proformance unless you need to pass emissions

Cant fill up 92 jeep yj gas tank. Ok till around $15 dollars and then the gas starts to spit out, like its full. Have to trickle the gas in very slowly inorder for it to not spit back or react like the...

sounds like your breather tube on your gas tank filler tube is clogged when you look at where you fill your tank youll see a little small hole next to the filler tube that is a hose that lets your tank breathe chances are it is plugged

Check your fuel pressure.
Hopefully this tank is not full, as you need to pull the tank to change fuel pump, this is mounted onto the tank through the top. There are several plastic fitting and hose connecitons on the tank as well as the fuel level connector. There may also be a Vapor pressure sensor on the tank. After unbolting the tank lower the tank just far enough to remove the wireing and hoses. Make sure top of tank is clean. If you have to move tank out from under Blazer cover hose aconnectionss and wash off top of tank and flange area. Unlock flange and R and R pump assembly. Reconnect hoses and wires, reinstall tank. Connect hose to fuel test port on engine, purge air from fuel system. Check the fuel pressure. InMrFixIt

Emission Code (Gas Cap) Could it be Pressure relief hose on the gas tank also?

yes it can be any part of the fuel system that is allowing air to escape, a way to find a air leak is to apply shop air to the fill neck while a helper listens under the car for air escaping, please be careful because gas can be pushed out with the air
