Fixed Pipe Uniform Load Support

[Reynolds7]

Hello,

I am working on a project to be able to support a spray bar assembly with a pipe with a specific diameter. The spray arms, fully extended, sit at 45 deg on hydraulics. To perform maintenance, these hydraulics must be turned off, so a way to support this is needed. The support pipe 103" long, will rest in two cup braces mounted to the housing. I attached a file to better show this. The support bar must be 103" long and no larger than a 2.5" diameter if possible. I am looking to figure out the smallest diameter pipe I could use to support this with a FOS of at least 4. This will allow for smaller braces on the housing, which is needed because I have minimal space to work with. Also, will smaller braces work? How many bolts needed to mount to housing? Diameter of bolts? The bar will not move side to side at all, obviously.
Any help would be greatly appreciated, I've been stuck on this for a while.
Thank you!

What are the distances between the load P and the braces at the end of the support bar?

12" from the load to the housing and then the braces will be an inch or 1 1/2" off the housing, due to limited working space on the housing.
