I'm having a terrible time getting the fuel lines apart. I have the special tool required both metal and plastic type. my hands are raw from the sharp edges of the metal tool. I'm about 2 seconds from cutting these lines apart. after at least 4 hours fooling with these lines and watching the videos I don't know where to go next. when I first saw the "easy connect" fittings I thought... oh good, these will be easy to get apart but now it's turned into a nightmare. this engine swap has been fighting me every step of the way. no room to work on anything. it took me 2 hours to get the hose off the bottom of the radiator because the steering componants and that stupid looking cross member where right in the way . I ended up just cutting the hose.

 

More information about the truck your working on will help. Year, engine, etc. If it is the colored "easy connect" connections by the fuel filter you are talking about, then you can usually just pinch them with your fingers and pull. No special tool is required.

 

1997 Ranger 3.0 V6 2wd and the fuel line and the return line connection is located near the wheel well on the drivers side. I'm pulling the engine. And I know it takes a special tool. I've just never had trouble with these type fittings before. there are 4 of these fittings in the engine compartment and I can't get any of them apart.

 

I just took one apart last week. I didn't undo the one your talking about, I undid the one that goes to the fuel rail. I struggled with it for two days. Once I was 100% sure I had the tool fully seated into the fitting I gave my Gorrilla strength, and then just as i thought the whole fuel rail was going to bend pull out the fitting budged. I then was able to wiggle it out.

It appears the o-rings where what was hold it together so tightly. I just put it back togethether today and I had to use an excessive amount of force until I hear the "click".

Looking back now, I wish I would have applied some oil to the o-rings when I put it back together. Because, now I am thinkgin if Iever try to take it apart again it will bind up again and risk damage to the fuel rail to get them to separate.

 

good advice, GOTRANGER? I think you're right I will use an o-ring safe lubricant when I put the connection back together. I did get it apart finally... After I basicly stood on my head and got down to where I could actually see inside the flange. I could see the spring was clear of the flange and I just needed to pull the connection apart. I was conserning myself with pushing the tool in far enough and didn't realize how hard I needed to pull the connection apart. the o-rings are what was holding the connection together in my case also.

 

I am doing the same thing and having so many issues with the fuel lines. Thanks for your comment. I will us more PB oil and see if that works
