Trust me you'll never be able to drill through the old one. Hardened steel just doesn't drill very easily if at all. maybe if you can grip it enough with pliers or something, but I doubt you can back it out that way either.

ya that's what i'm thinking to. buuut i think ive got some other bits that are a little bit harder than the bit i used. if anything i'm out the 8 bucks i paid for the tube, ebay special:hehe: i'll prolly just buy a bunch of em and drill on em til i get it right. you're prolly right tho about not bein able to drill thru it. we'll see :party018:

Well if you're lucky you might be able to get it then use an easy out... but Ive never had any luck with those, always seem to drill it out good and then when you try to get it out it snaps off too. Maybe it's just me :confused013:

once in awhile I've had a little luck using a air powered engraver to vibrate the broken bit out by cranking the engraver to its high setting then pushing on the drill bit to rotate it out back words if there is enough bit that you can get the engraver on it.

Just a thought if you have one.

Good luck.

Are you using any lube? I seem to have good luck using an aerosol metal cuting fluid I get at NAPA. works better then WD40.

Its not hardened steel. More than likely what happened is you got the bit a little crooked and it broke. If you put the tube on a lathe they cut like butter. My drill bit still looks brand new.

I'm not sure which way you were drilling, but if you went from then end that is towards the injector you can drill out the edge filter and push the broken drill bit out the way it went in.

:ditto:

Make sure you drill them from the injector end when you drill them. This may help avoid broken drill bits.

are you using any lubrication? motor oil works fine
yessir i same motor oil i put in my cummins actually...but yeah i guess patience is a virtue. i figured if i could get it right on the first set of tubes id put them in but since i screw it up im not worried about it, just gives me an excuse to do something else haha

I hate to steal teh thread but what all does drilling the connector tubes do for you? I just replaced my connector tube orings and so it was the first time I dealt with them.:confused013:

it reduces the obstructions to fuel flow. if you ever have to take your tubes out again, try looking thr them. you cant because of the edge filter. take the edge filter out, drill the hole to .093" and voila you can see how much less restriction there is. it is a matter of opinion to some ppl if it helps or not. i believe it does just based on the fact that it reduces restriction. i don't care either about ppl sayin that timing is retarded due to lesser pressures caused by the tubes being bored out. i believe it helps and that's all i care about:lol4::lol4:
