LS Steam Vent Lines Trying to decide if I should cap the tears and just run the front or move to a four corner system. Not going to pay Kurt Urban prices in this but also not seeing a lot of options for setups that work around a FAST LSXr manifold. Any suggestions?
Also, in the event I reuse the stock LS3 front line, where to I get the o-rings? Seems I lost one in the tear down last year. Thanks.

I'll be drilling and tapping my LS7 heads and making my own lines. I'm also using a FAST 102 intake. The -4 AN fittings that go into the back port locations were 15$ from Pep Boys. Just need to buy some -4 line and some more fittings. I can't see having much money at all tied up in it, and if you wanted to get real cheap, get some brass NPT fittings, barb fittings and rubber hose.
For the front o ring fittings, I would imagine you could get them from any auto parts store

If anyone has some photos of their setup with a FAST/factory style manifold I'd be interested ins seeing them. Thanks.

Makes sense. Wish I would have thought about that earlier. As it stands, too far along in assembly to go back so going to have to look at other solutions for now.

Thinking of going stock on the front and LQ4 line on the back and tying them together. Other thing I am thinking about is just bending my own hard lines. Comparing cost for the fittings to see how much that would be.

I ran the factory coolant lines under the Fast 102. It took about 4 hours, but I was able to slowly tap the lines to more of an oval and got them laying flat against the valley cover. Then shaved a very small amount of material off the bottom of the intake. I pressure checked the lines before the final install and all lines ran water without leaks and everything fit like a charm.

LS Steam Vent Lines So here's the solution. Front steam vent lines from an Escalade, some stainless tubing and Swagelok brass fittings. Total cost about $35 for the Escalade piece and a hookup from a buddy on the rest. Turned out really good.

LS Steam Vent Lines I think there are some pretty nice setups out there but I am a function over form guy first. If I can have both that's great too. One thing I like about this particular mid is the simplicity. Looking good for many of us so far.
