06 3500 hydroboost question

[kilroy2981]

Hey guys, I went to change the hydroboost on my 06 3500. I took off the 2 high pressure hoses that go to it and I noticed that the o rings looked like crap. Does anybody know what size they are so I can get new ones? Also, the low pressure hose at the bottom of the booster, the one that gets a hose clamp, looks really crappy, does anybody know where I can get a new one. I checked online but I cant find the exact hide I need. It might be part number 4581635AB, but I'm not sure. Thanks for any and all help.

I think it's this one next to 11

For the return line you can use a standard part like i did, it's 11/32" transmission fluid hose.
I got mine from Amazon but virtually any car parts store sells it by the foot.

Hi,
Dumb question but how did you know it was time to replace this? Any symptoms or issues? Or are you doing mainly preventative?

It was leaking into the cab and making whirring sounds. If you look at the rod connected to your brake pedal, and see red fluid, the hydroboost is leaking
