Broken Fuel Pump Flange

You can try to get it out, best option is probably an EZ-Out of some type, square or round, your call. I have had decent success tapping threads in the broken piece and running a bolt through it, then pulling the whole mess out.  You can also crush/mangle/drill it to pieces and flush the oil a couple times, this is also considered sort of acceptable due to it being a bake-a-lite piece, not metal, and thus the shavings and small bits that remain in the motor will be pulverized and not hurt the internals. (much...) If it were me and I wanted the car on the road soon, I'd just put the original broken piece back on top with a new gasket and call it good. Forget the superglue, it's all oily and it wont' hold anyway. The lower piece isn't going to fall into the engine due to the taper, and the stresses on this part won't really be affected by the break, it's just a bushing for the pushrod. Replace it when you rebuild the motor.

Good Luck,
