Changing a fuel line hose..quick connectors

I need to change one of the rubber fuel line hoses leading that comes
out of the sending unit on a 93 Sundance. It looks like a pretty
straight forward operation however I can't determine how the "quick
connectors" go on and come off. It doesn't look like there are any
clips or anything of that nature to loosen or tighten them. Can anyone
enlighten me as to how they work and is there anything special I should
know about the process of changing the fuel line? I know that I have to
somehow relieve the pressure in the system although I 'm not quite sure
how to do that.
Any information would be appreciated.

 

I have been told that the term "quick connector" may be incorrect in
regard to my previous e-mail. I am referring to the bands at either end
of the hose that hold it in place. They are some sort of clamp but I
don't know what their proper name is.

 

Take a screw driver under the thick side of the clip. (pointed side) and pry
up. They are a u-shape clip and slip on and off fairly easily.

 

Thank You !
Do you know what the correct name for them is?

 

You mean the hose clamps?

 

No, I think quick-connect is an acceptable term. Replace them when you put
it back together. You can get them from any parts store. usually come with a
new fuel filter and/or pump.

After further research I found that I was mistaken about the parts
involved and how they fit together. Apparently the end of the quick
connectors slide into the rubber fuel line hose and there is another
ring of some sort that fits around the end of the hose and secures it
to the quick connector. I thought that I could just take the ring off,
slide the hose off of the quick connector and then put the new hose on
with a new ring. Apparently it would be just as easy to take everything
off including the quick connector. This brings up another question: how
does that ring secure to the end of the hose?
