Broken thread on Holley Fuel Bowl - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

After just changing jets I managed to strip two of the threads in the throttle body on the fuel bowl bolts.

Has anybody got a fix for this sort of thing...? Hopefully not a new throttle body!

Just helicoil them. I stripped one on the 850 Barry Grant i had, and just helicoiled all 8. It is not bodgy at all, but better than new. We sell the kit at work, and off the top of my head it was 7/32. Works great.

Fill damaged holes with 2-part epoxy, liquid metal, or similar product. Wait until cured, then drill & tap. Temporarily install bowl to use as a guide to align drill.

like 'xdclevo' says, Heli-coil is best if you can find that size kit. When I needed it, I couldn't find, so I used liquid metal.

I did the same just this week with the plunger screws. I was lucky though cause a could retap them with a slightly larger screw.

Yeah just as an update the heli-coil kit was the way I went, but it was a bit of a hassle tracking one done.

My Holley is better than new now.

Just curious,what was the exact thread you got?

Don't know, it was a carb shop that did the work for me.
