Thanks for all the input guys. I ended up setting up just the wastegate line with the push-to-connect fittings and plastic line and it has been solid as ever. All my other line is rubber with zip ties, and I went over them all and made damn sure they are all nice and tight. Anyways, thanks for all the input everyone!

And thanks to camaro9969 for the section of plastic line! I know it's cheap, but it was still free for me lol.

I'll be using -4an lines on the wg and bov for cleanliness and to be safe. But those quick connect fittings seem cool. I will have to look into them.

i used the quick disconnect fittings like listed above, got it all from mcmaster.com 26lbs, street driving, track driving, no hassels, and super easy to take off and replace if need be, (vice cutting zip ties and then re zip tying)

I found those fittings from Grainger for 30$ each.... Who has them the cheapest?

Edit- just saw that link to mcmaster-carr. They are a little more reasonably priced there

I recently had my wastegate line blow off during a pull which caused it to overboost, and it cracked piston 7 and bent the rod. Threw in some spares I had laying around and it's up and running good again, but I would like to set the vacuum lines up so this doesn't happen in the future.

Biggest problem area I have is that the ports for all my turbo accesories, like the BOV and wastegate, use 1/4" line. However all the ports on the stock LS6 manifold are around 3/8" to 1/2" or so. So basically I have a section of 1/2 or 3/8 line off the manifold into adapters to go down in line size for every vacuum line, and it's cluttery and just too much BS going on for a possible issue down the road.

So like I said, any pics and tips would be much appreciated!
Had the issue with my wastegate fittings being 1/4 and everything else being 3/8 or 1/2. Literally just ordered some 1/4 to 3/8 pushlock adapters and some 3/8 and 1/2 pushlock 90s from amazon to avoid the janky look of sizing down the line. Nice to see a lot of people have already done this because I didnít know if the push locks would work on the ls6 nipples.

I use the 1/4" pushloc lines, and off the intake I will use a comp. fitting with an adapter since there's
just a smooth nipple, no ribs to hold the line.

I am using the 3/8 nipple on the intake and the 3/8 on the TB to tie into my wastegate with pushlocks. The 3rd port on my WG ties into my co2/ boost solenoids.
