Anyone know the part number of the hose labeled line 4 that connects to the boost control solenoid? Mine is split and when I brought it to Stevens Creek Subaru the guy working the parts department couldn't find it, then told me he "gives up" so I guess I need a part number to get this.. Thanks

 

Just go get some at an auto shop. That's what I did and its been working fine for about 8 months - I don't recall the size though; I think 1/8" ID and OD really doesn't matter. Here's a tip: replace all of them because if one is cracked, the others are going to also. I know this for a reason

 

yep they wont give you any information without a part number and your last 8 digits of your vin lol!

 

Ya, buy enough vacuum line to replace 2 and 4 cause more than likely the other one will crack soon

 

Cool thanks guys, yeah I was just gonna replace the one but might as well do them all while I'm at it. I still might go back to Subaru with my VIN though, I'd rather have the OEM part, I just hope the same guy isn't working lol

 

The reason I say that is because the piece that connect to the boost control return hose his larger then the other side

 

I used the same hose that I used for the solenoid for that one because it cracked on me too. THAT one in your hand is VERY expensive and I do have the part number for it because I bought one - I can get the part number for you. It took two weeks to get, which is why I did a little DIY with vacuum tubing from Winchester. Take a chunk in with you and get whatever has the same ID. You may need all the little fittings that connect them too, because some of those cracked at the same time

 

Thanks 04GG, but I went back to Subaru and we ended up finding the parts! If anyone ever has the same problem these are the three part numbers you need to complete the hose. Hose-Vacuum (connects to boost solenoid return hose):99071AB481, Conn-Hose 16385AA030, and Hose-3. 5X7. 5X495: 807503820

 

Was kinda expensive though, $32.60 for everything..

 

OUCH!! No thank you! Return that **** and go spend $3 on 2ft of vacuum hose at autozone. Then spend the remaining $30 on wine

 

vacuum hose......... $3........................................

 

**** you got ripped off when it's just vacuum hose to begin with.

 

Haha its all good, I'm not tripping about it

 

The little fittings that connect the hoses are stupid expensive too. My total was around $46, but the hose that I used to actually fix it cost me about $1.50 and I have like 2ft left.
