So I just bought this brand new fuel filter tool that is supposed to work to un-unconnect the "quick connect" type fittings on the fuel line that connects the fuel filter on my 98 ranger. It has two different sizes available, one on each end, one for 5/16" lines and the other for 3/8" lines: http://i207.photobucket.com/albums/bb153/sgull1/IMG_1830.jpg You're supposed to be able to engage the tool onto the whichever size line fitting (mine is the 3/8" size) and by pushing in be able to release the fitting off the fuel filter tube. Trouble is, when I try to surround my 3/8" end of the tool onto the fuel filter tube, both halves don't slip into the fitting like you'd think they're supposed to. When you close the two halves over the tube they don't meet into a perfectly round circle, it seems one half of the sleeve is slightly offset from the other and therefore doesn't fit into the recess together along with the other half l. All I can do is open the jaws of the tool and slip one half onto the tube and push in. One half will push in, and I seem to be able feel the resistance of spring tension in the fitting as I push in, but I just can't get the connection to release this way. I push in the one half of the sleeve (into the fitting and away from the filter) with one hand, and with my other hand hold the end of the fuel connection there and try to push/pull on it at the same time while I'm pushing that half of the tool sleeve into the fitting. I tried this over and over but it doesn't want to release, even with considerable struggling and pulling/pushing. And you can only pull/push on the line with reasonable force there's obviously a chance the fuel line or the connection will break or be damaged. Anybody familiar with using a tool like this on the quick connect fittings as used on a 98 Ranger fuel filter please describe what the trick is here please. I'm beginning to think this tool is defective, doesn't seem right to me that one half of the sleeve should be offset from the other and not fit in together around the filter tube(s). On looking close at those two half sleeves on that end of the tool, it seems the problem is that they don't meet together properly, that one half is slightly offset or tweaked away somehow from the other half, and that seems like what prevents both of them from slipping into the fitting at the same time. A couple more photos (kinda blurry but you can get the idea): http://i207.photobucket.com/albums/bb153/sgull1/IMG_1836.jpg http://i207.photobucket.com/albums/bb153/sgull1/IMG_1834.jpg any comments/advice appreciated.
