Default Boost prepping 51ida Weber

Im looking to boost prep my 51ida weber (7-10psi max on stock s5 turbo). From what I read I need to do 2 things for sure.*

1. Vent the fuel bowl into the carb hat so it sees the equal pressure. (Line from fuel bowl to carb hat area?)

2. Swap the brass float for a plastic float. Because the brass float will crush above 6psi. The plastic float is good until 20psi.

Other things I have read are unclear. Its obvious that i need to seal any and all areas that can leak. But what areas do these include?*

1. What else besides the "hat" needs to be a sealed?

2. Do I have to seal the throttle shaft?

3. Is there any other modifications to the weber that need to be addressed?*

I have everything else ready to go. I just want to be sure I get my weber in order before setting it all up.

3.3 needle valve, machine carb top to flow more fuel, enlarge float bowl, if the carb hat is made properly you dont need to vent float bowl, (like the carb hats i sell) phenolic float.. i sell i complete IDA boost prep kit, comes with all parts needed and instructions..
