Default HELP *** Quick Disconnect *** NOT

I'm trying to disconnect the fuel line from the fuel manifold using a 3/8" plastic disconnect tool and it will not budge. Anyone with any ideas??

Thanks,

BJK

Is the tool high quality...maybe it is bending/ disforming under pressure or it is not fitting/inserting correctly.

Goes with out writing yes, you did read the instructions?

Perhaps spray some penetration oil into the joint.

That line can be tough to remove sometimes. I'm not sure why, one time will come off easy and next time a battle. Maybe the tool ?

It's a hard plastic and I'm using the same instructions as in the shop manual. I had just thought of trying a little engine oil as that is recommended when reinstalling.

I'm thinking of going to Harbor freight and getting the metal set. Maybe it has something to do with the thickness of the plastic. My problem is that this is the first time I have tried this, so I don't know what the inside of the quick connect fitting looks like.

I'm really not sure. I just know during a recent repair my mechanic had it off many time. Sometimes it would come off easily and others he would swear and fight with it. I remember he had a few disconnect kits and was trying various ones. Sorry can't help more.

I just got a pretty good look inside the connection and I can see two large metal tabs that need to be depressed and I'm pretty sure I need something that is a thicker. I can feel the plastic tool compress them as I insert but I don't think it is thick enough to fully release the clips. I might try wrapping the out side of the tool with something to make it larger and therefor depress the tabs more.

While the metal tool works a lot better than the plastic, I used to have trouble occasionally even with the metal one. What I've found that helps is to push the two fuel lines towards each other a little bit and while they're compressed try sliding the tool in. It takes a little practice but ever since I've adopted that technique they always come apart easily.

Hope that helps.

Thanks, I also tried pushing them together, pulling them apart, and tipping them in just about every direction/combination with no luck. I really think the walls of the tool are to thin. I'll be going out to pick up a metal one and see if that helps. I also tried the connection at the firewall with the same bad results.

Default Problem Solved

My hunch was correct. The o.d. of the Harbor Freight disconnect tool was to small to depress the tabs enough to release the connection. I picked up a 3/8" Angled Fuel Line Disconnect, part number 39420 by Lisle Corp, from O'Reilly Auto Parts. Much bigger o.d. and I could feel the greater resistance when I slide the tool in place. Bigger is definitely better in this case. (price was $3.49 plus tax)

I went through 3 disconnect tools before I found one that worked. I finally got a 3/8' (or maybe 5/16") red anodized aluminum tool from Discount Auto Parts to work on the first try.
