I have had to bush the hole in the float bowl cover to repair the wear.
I agree. The hole looks too small. Daytona Parts said they swelled up after being soaked and typically used a garter spring. When I bought the extra NAPA plungers, there was a small bulletin regarding leather seals. Daytona Parts also said their plunger seals were ethanol resistant and used a harder rubber so that the seals did not curl up and tear, which is what happened to all three of mine.I don't see any way this leather will work for the pump.

Apparently with the Daytona kits, the thick insulator gaskets do not present a problem needing longer studs. For my bolt needs, I use a local supplier called Palmer Bolt and Supply in Piqua Ohio. Grainger may be a source, or McMaster-Carr. I don't know about Fastenal. To have them made would be costly. you'll just have to google searchWhen I first rebuilt the triples on my Impala, I used a mass produced kits sourced from a big chain store, the rubber pump seals all failed, folded back and tore in the first week.
I called Larry Fulton at hotrodcarbs.com and bought the 3 pump plunger assemblies, connector links and 1/2" thick insulator kit and airhorn repair kits. Been fine since that. The new plunger assemblies were rubber as well.
On the insulators, what are others doing for longer vented studs? Do I need to make them?
I can get longer studs, bore the vent and turn down the end for a vacuum hose. Only need 2 vented ones. Doubt anyone sells them.Apparently with the Daytona kits, the thick insulator gaskets do not present a problem needing longer studs.

Is this the stud you need? https://www.ebay.com/itm/323816338564?hash=item4b64f53484:g:B6QAAOSwu1VW6WuVI can get longer studs, bore the vent and turn down the end for a vacuum hose. Only need 2 vented ones. Doubt anyone sells them.

I think you're going to have to custom-make your own. Be aware that there are two different threads on this stud.Thanks for the suggestion.
No, to short, I have the OEM ones but will be adding 1/2" phenolic insulating spacers. The OEM studs are short for this particular application.
