Snapped fuel tap

Post by aseleven »

Hi everyone, while fitting a new fuel tap today I may of been overzealous and tightened it a tad too much snapping it off 😔 I've tried using a screwdriver to get the remnants out, but it's not really working, any suggestions is it a machine job or can I drill it out?

Many thanks in advance

I might suggest now you have drilled it out, go to your local engineering tool suppliers for a tap and retap the thread,job done.

Is it not possible to remove it using one of those LH thread type stud removal tools. That may save messing up the thread. It does not even need to be drilled first to screw in the tool. As you screw the tool in it should start to unscrew the broken bit of the tap.

You should be able to remove this easy unless you have used to much force that caused it to snap.

Hi

It may be easier to screw it all of the way into the tank and then remove with a magnet.

Hopefully the tap is made of brass so no good using a magnet there!

These are Easy Outs - as mentioned are like a L/H threading tap. You insert these like you were going to cut a thread but you turn it anti clockwise whilst pushing the easy out into the hoe with a little pressure, when it bites into the piece of the brass tap it will unscrew it.
They are cheap as chips to buy. Be careful not to contact the steel thread on the tank or it might graunch it up and do not use too much force to turn it because it is a right pain to remove a broken one - they are hardened and therefore brittle - if you feel it flexing then STOP!

Agree with bitza. Try picking out some of the embedded old material, which will be soft, then carefully run a taper tap through.

In my experience of using easy outs great care is called they will snap of in the blink of an eye if to much muscle is used, and I would think if the broken fuel tap is brass might the easy out cause the brass the spread when trying to remove broken part especially if it had been over tightened before it snapped off.
