My fuel pressure regulator has the vacuum port on the top (flex fuel) rather than the side, no where can I find the right vacuum line elbow that is 90 degrees, only the 45 degree slanted one. I tried a generic 90deg rubber elbow but it cracked after a few months, anyone have any ideas or the same issue?

the most common 45degree connector below:

I don’t think this is it, but just in case.. (meant to say: just in case it will work) this is one of the lines that came with my TBSS Evap swap kit: 12574897:

Damn, that was fast!

Gotta get out the calipers..
Ok, after many, many hours.. many hours… I finally measured the best I could with my cheapie calipers. They don’t have a long enough throat, to reach the middle of the indentation for the clamp, so had to just measure across the top.. so the measurement includes 2-3mm of the ridge unfortunately. Anyway, that measurement came out to 101mm, so at least I have an idea of what size I’ll need for the intake tube.. now to find one.!

ETA: It is an OEM LS3 throttle body (just ported), so whatever kit fits that may work, with some adaptation.

Googled this up right quick: https://ls1tech.com/forums/generati...-oem-90mm-dbw-throttle-body.html#post16215623

He said 4", which makes sense. You measured 101mm and 4" is 101.6mm.

Care to share the link of the outer scraper/seals?? I'm thinking these are the felt seals that ride against the glass on top of the door, if that makes sense. Mine are brittle and broken

Finally finished painting the dash and got it back together. Feels good to get it all the same color and back in business.
