With a NOS part (they would have used old style diaphragms and parts) I wonder if what you’re seeing is not caused by the fuel we now have? Alcohol can deteriorate the rubber parts quickly some areas have more added into the fuel than others.
That interesting, cause the mechanical airtex pumps I've seen are new castings. The base looks a little like a carter, but really like no other stock pump I've seen. I've heard more than a couple horror stories about airtex, both mechanical and electric. They seem to be the low cost (import) leader.
You're right though, might be something to watch on these 'NOS' parts...I should qualify that term, because both these are older stock, but are acutally rebuilds of factory original pumps (the carter is a BW rebuild, and the '66, pictured above is an old ACDelco rebuild...but I imagine they could very well pre-date ethanol).
So anyone own/use a combo gauge like this one :

I'm actually looking at vintage snap on models, but don't want to pick one up if it does neither job very well...could use another vacuum gauge cause mine's on 'permanent' loan to my brother and his dogged '66 cheby truck :roll:
Will probably use a autozoo fuel pressure loaner this weekend to at least make sure the carter is not way over board and get the regulator ordered.
Found a post here about a redline regulator so I'll check that out...many I'm finding range from 5.5-9psi IIRC and I'd like to have the ability to adjust a little lower if necessary.
Thanks
