Tinkering with my car yesterday I noticed that a fuel inlet fitting was loose where it screws into the carb. It wouldn't tighten up and I presume the bowl threads are stripped. Not sure why, although I either partially stripped it many years ago during instsallation, or over those years the weight of the fuel line rocking back and forth under vibration stripped the threads. Maybe some of both.
Looks like the P/N for a replacement bowl is 134-101, but I notice they also sell an aluminum bowl, P/N 134-76C. Holley doesn't say much other thna there's a weight savings, but I'm wondering if it stronger and will hold up better than the zinc based bowl. Any thoughts?
Below is a picture of my installation:
