look up WIX# 33737. thats the one that Im going to use.

 

did you manifold already have the seal for the throttle body? The one that goes between the mani and the tb? would you happen the have the part # for that seal? Thanks

 

does the single out slide rite in to the tbss stock fuel line ?

 

Andy, I don’t know if it’s the same part number or not, but the seal for the 90mm LS2 throttle-body is 12576549. Unfortunately the thing is $43 to figure out whether or not it’s correct. It would be a damn shame if it didn’t work, so I would have to check with someone before I shelled out for it.

 

ok one thing you need to do , is get that fuel filter OFF the fuel rail.
why? cuz its crimping the return line behind it and affecting your fuel pressure.
how do i know this?
cuz i did the SAME thing..

 

Post #30 is how I'm going to route mine.

Thank Bear for the part number gmpartsdirect had it for 30 shipped.
any idea if that will work on the NNBS intake?

 

So bon how did you take care of the return line being pinched ?

yes TBSS already came with it. dont know thw part#

 

that filter, on the tbss rails doesnt quite slide RIGHT in.. you have to bend the rail slightly to get it to fit.
to answer what i did.. you get a 18 inch length of fuel line, one end female.. shove that on the rail, the other end a mail an fitting,, slide that into the fuel filter and zip tie it in place.. that pulls the lines AWAY from the firewall and then they arent pinched.
the 33737 is female on the front, dual males on the back.

 

here is what mine looks like,, but this is not my pic.
