Today I'll be replacing the fuel dampener. I also replaced my fuel filter last week and turns out I did not go through the process properly. All I did was just clamp the two fuel lines shut and disconnected the filter and replaced it with a new unit. I was told that I should of depressurize the system first and do the replacement.

My question is, do I have to depressurize the fuel system to replace the dampener? How do I depressurize the system?

 

Start the car and pull the fuel pump fuse wait til car dies....Am I wrong?

 

Nope.

 

Thank you guys

 

Or you can do it the hard way and disconnect the relay under the driver side kick panel. The first time I did it this way bc I was a noob back then. =).

 

they have a fuel dampener? so how exactly is it getting the fuel more moist? this invention intrigues me...... hehehe...

 

I thought it was to eliminate the pulsing?

 

You did fine by clamping the line shut. You do not have to relieve the fuel pressure before removing a fuel line. It will relieve itself when the line comes off. I usually wrap a rag around the end of the first line that I'm removing to prevent the fuel from spraying everywhere.

Even if you remove the fuse or relay and run the motor till it dies, there'll still be 30+ psi of pressure in the system.

 

@napoleonzheking - thanks for the "longcut" lol.

@CanyonCarver - thanks to you too sir . I didn't have any problems by not depressurizing the system before but I was concern since people were telling me I did it improperly.


Again thanks to everyone

 

i was poking fun that its a fuel damper. dampener implies something that will making something else more wet. haha.

 

But it says "dampener"... http://www.z1motorsports.com/product...roducts_id=639

*shrugs*

 

Both terms (damper and dampener) are generally accepted for the name of the device that smooths the fuel flow. (Google both and you'll receive info on the same device.)

However, Eric is right, it's technically called a damper. To damper, in physics, is to decrease the amplitude of (an oscillating system).

 

holy crap does every thread have to turn in physics class?

 

Ummm.... yes! Physics is one of the most important sciences in the modern world. ^^


Anywho.... some places do call it dampener, but much less than the ones that say damper. It is a common misconception and some how became accepted as normal. It is wrong though. Not a big deal, but i just get bothered by that specific term. Mostly because for the motorcycle people on the kawi forums many times say steering dampener, which its a steering damper. DAMPER!!!!! lol.


Also if you do Google fuel dampener, all but a select few pop up with damper, Google knows your wrong!

 

It's a car forum... modifying a car to perform better is to modify a car so that it better uses the laws of physics to its advantage...

 

can something be more wet? If your dead, and i walk up and shoot you, your not going to die again or be more dead, your already dead.... haha

that was part of my sarcasm.... lol. dude look it up if you don't believe me. a dampener would imply an object that renders things more wet. lol. to dampen: make moist

so dampener would be like, the make moistier or something.

make moistier?? hahaha that is totally not a word...

but still, you can't make something more wet.... if it's wet, it's wet

 

Ah... Gotta cha.

Thanks for clearing that up guys.

 

i know, and.... i know. thats part of what im saying! haha. and moistier was the only way i could describe it in one word again. pardon my awkward word coinage.
