Re: Thread Repair Holley Fuel Bowl

Tim, Read all the remarks. If the bowl were very valuable then a good machinists could make an insert to save it. That's if you had enough wall thickness.
So you do have a few threads you say. Here is a cheater.
Go to CarQuest or NAPA and buy Loctite 271 aka as Threadlocker Red. High Strength. I goofed this past summer and used it on a brass T fitting on a 62 FI unit. The fitting screws into the aluminum diaphram cover. Well I didn't quite have the angle of the fitting correct. So I tried to move it a tad with zero luck.
THis 271 is permanent.
Bubba way is to: PC 7 Epoxy. Eastwood sells it and so do a lot of hardware store.
Do one of the above while looking out for another casting my friend.
McMaster Carr doesn't list that thread. They have 9/16-18 but nothing finer. JD

Chief Bubba FI repairman, Loctite has a thread release agent with the kit. You can take it apart again if you should so desire. PC 7 is kinda like permanent.

Re: Thread Repair Holley Fuel Bowl

Thank you all for the help, I appreciate it very much.

I found a fellow in PA. that has some 9/16-24 helicoils and he has done a few of these bowls. After speaking with him he knew exactly my concerns and said he can repair it no problem. I am sending the bowl today and when it comes back I will post some pics and info for everyone so it's in the archives.

I too am not comfortable with any epoxy repair and why Holley used a 9/16-24 thread I can only assume they want you to buy a new bowl. Problem with this on the original 2818 is that there are little casting goodies that are unique to early bowls and this bowl is in V/G condition..
