Dreaded plastic Fuel Coupling

Hi all. I initially found this site whilst researching a solution to an issue I encountered whilst working on my Daytona 955i. I was re-connecting the fuel lines to the plastic coupling when it broke clean off. (The female coupling into the side plate of the fuel tank) After a minute of pure horror I went straight to the website and found that on this site a few posts which informed me of the common issues with this part and it directed me to a metal replacement (1/4 BSPT coupling) It also pointed out the issues members had removing the broken plastic thread left inside the wall plate. I found an Australian supplier who provided the part from “Quick couplings” LCD10004BSPT - 1/4 BSPT Valved Coupling Body called Vicfit sales. They posted the parts overnight. I then went to tackle the issue of removing the broken thread. I read that some members spent ages picking the plastic out with a fine point pick etc. I came up with a quick and very effective solution which worked a treat. I grabbed a number five “easy-out” from my kit. If you don’t have a kit I believe you can buy them individually anyway. They are only a few bucks each. I then cut about 8mm off the tip with a cut off grinder so it fitted just inside the broken thread. I then heated the tip of the easy-out up with butane bottle. Not too hot and pushed it into the plastic using a spanner which fitted the head of the easy-out. As it went in it slightly grooved the plastic. Once I felt it bite tight, I let it cool completely. Then I simply undone the thread using the easy out in a couple of seconds flat. No picking and clean as a whistle. Major relief. The new fittings went straight in. I hadn’t seen this option to remove the thread so I thought I would post it. I hope it helps those in the future who encounter the same problem.

Good job - and great to pass along the tip for others.
I saw a similar tip for a heated screwdriver pushed into the plastic also that a user had some success with.
Nice thing about the EZ-out though is it will bite more as you unscrew it.
