I have a 76 F100 with a 360 and a motorcraft 2150. I was replacing the fuel filter which screws directly into the front of the carb. I screwed it in by hand most of the way, went to snug it up with a wrench and snap! the threaded end broke off in the threads of the carb where it screws in. I dont know if the threads in the carb where damaged by the previous owner, or if the filter was a POS. Does anybody have any suggestions on how to get this piece out without damaging the threads on the carb? There is nothing to grab onto with plyers or vice grips and the metal it is made out of is really soft.
easy outs aint always the answer because when they break there a big pain to get out because there hardened. if you break an easy out in the carb probably kiss it goodbye. I learned that the hard way. I broke a easy out in rearend cover bolt, and to get easyout out you have to use a carbide bit on a die grinder .
I would use a left handrill bit , they work because when you drill your goin oppisite way and will unthread itself.
I broke one off once and used an easy out to remove it. Came right out. I used a helical flute easy out but a straight flute may work better. The spiral flutes can expand whats being removed.
If it did not break off flush with the carb body, take a Dremel and cut a slot on its head and use a screwdriver to back it out. A hacksaw blade will work too but ya gotta be more careful.
edit: Oh sorry - re-read the thread... It's IN the carb body.... EZ-Out!.. Or drill it out until it crumbles.
I threw away every ez out I had, but this is one instance where I would try it. I'd never ever use one again on a block or head. Carefull though, carb is easy to crack even just tightening the filter.
Thank you all for the advice- Im gonna get an easy out and give it a shot. One other question- how tight does the new filter need to be? I am assuming just snug with a wrench, but does it have to be all the way in until the shoulder of the filter is up against the carb? I dont see how it seals if its not all the way in there.

It doesn't take much. Get it hand tight, then another half-turn or so with the wrench. The filter will not be flush with the carburetor; it will still look like it's sticking out. The tapered threads are what give the seal.
Well, disaster- I used the easy-out and it gripped the broken piece really well but it just wouldnt turn- I have never seen something so seized up! I turned and turned and then the carb cracked. I think someone had damaged the treads previously. Does anyone know where I can get a cheap rebuilt carb? It looks like rock auto is the cheapest. I have thought about getting an old one at the junkyard and rebuilding it myself, but that might be beyond my skills.
CAREFULLY drill that thing out and tap it with an NPT thread, install a brass hose barb and run a very fine inline filter between the fuel pump and the carb. If you don't feel comfortable doing this, take it it a machinist and pay $20-$30 to have it done. Should be cake. This is what I did for the stripped filter threads on the 2v carb on the Bronco in my sig
