I don't think its for the brake booster. Our brake booster line has a one way valve in it. Without it the booster will not work properly.

There is a label attached to a long hose to specifically use a valve.

Ok so I just put 7 of the 9 hoses on my 03 the other day and don't really know why nobody has tried the brake booster hose. It will fit... I think... i held it up in place and it could I assume however with a slightly different routing. The guys in the UK have and I understand they're different being RHD and all but if I cut out the one way valve and shoved it the hell in the samco one I assume it will work...? My car is my DD so I don't really wanna be the test dummy...

Lastly my "coolant under tank hose" did not fit at all the ID of the hose was wayyy small. So I have that one sitting around as well.

I just installed hoses on my 2002 wrx. And this shorter hose you speak of does not fit on the bottom of the coolant reservoir unfortunately.

Has anyone had problems installing the coolant hose under the resivouir. I'm having trouble cause the I.D. Of the hose is way to small to fit over the nipple.

Edit- nvm I missed the last three previous posts lol

Ok so getting off the resevoir coolant hose I broke the plastic hose with a red stripe above it. Any idea what this hose does? It goes form the air intake somewhere. Maybe some sort of vacuum test? Anyway I wondered if I could just get any hose to replace it or need something hard plastic like it seemed to be as well as what the heck it is. You can see it in picture five next to coolant tank (mine had a stripe on the side toward coolant tank).

Thanks, I can't find it in the oem catalog so I will just put some hose over the cracked pieces and hope for the best . Anyone know a part number for the under coolant tank hose? I stupidly got this kit b'c I had a leak somewhere. Yeah that was where the leak was and the new hose doesn't fit of course. I tried to buy some hose at the autoparts store, it was cheap, but kinked. I am not sure if it will be a disaster or not with the kinked hose, but it sure seems likely to me.

https://www.partswebsite.com/stores/...s7/7591040.gif
Of course that doesn't list the silly hose that I need for some reason. There was a bunch of corrosion on the metal part the hose connects to on the engine it is a bummer.

Hate to bump an old thread, but I had a quick question. Do you need to drain and refill the coolant? I watched the Mishimoto install video and they said to drain and refill; is it really necessary for installation of the hose kit?

You would only need to drain it enough that it runs out of the hoses you want to change. I've only completely drained it when changing the radiator.

just pull off your lower hose and drain in a clean bucket. Refill/burp.
Its the quickest way.

Otherwise you can try clamping with radiatorhose pinch-off pliers to minimize draining.

Thanks for the comments guys.
If I were to drain and refill with the same fluid, would I need to add new coolant additive?

If you don't have any real spills, just top it off (if it even needs it) with some distilled water. A gallon is less than a buck at the grocery store.
