Is there a list of the pipe plugs and or fitting sizes on this manifold? Looking to order off of summit. Just need to verify before I order. Thanks in advance

 

all of the pipe plug and fitting sizes will be listed in the instruction manual

 

It wasn't listed in the instructions:/

 

There are probably 6 places that may require a plug if ports are not used. The following are usually included with the install kit.
2ea—1/2" Pipe Plugs
1ea—3/8" Pipe Plug
3ea—1/4" Pipe Plugs

These plugs can be had at your local hardware store off the shelf, I would use brass.

 

If you're really ambitious you can use this chart to determine what you have and go from there.

I agree. No need to order from Summit.
