Hose's on Throttle body
« on: 16 January 2004, 16:36 »
I've just noticed trying to find the vacuum hose for the MFA MPG reading that one of the hoses on my throttle bottle has been blocked with a screw !!!

The one that's connected to the Fuel pressue regulator is fine it's the one next to it - where the hell should it go ??

And I still can't find the vacuum hose for the MFA - where's it connect on the engine ??

I know this probably has been posted a few times but please help !!!!!  ???

you have a mk 2 gti..... the mfa is connected on the brake servo hose whichs connects to the right side of the inlet manifold! the mfa tube connects on this

normaly the little plastic pipe which is slid onto snapps off but you sould see another little pipe next to it with a green cap on use this and then tape up the other hole......
 
as for the tube with the screw in you have a screw in this because you have a k&n filter (this tube did go to the air box) you can either leave it or by a little rubber cap! if you do this you wont need this pipe.....

mine has a rubber cap on as this pipe which runs to the air box was joined by a t connector to the fuel pressure reg pipe!!!!!!! ;) ;) :) ;D

happy now...... ;D

Cheers for the reply but that's not the right hose ...

I had the bolt on the suspension turit snap off over the weekend, so the old air box has gone back on for now. The throtttle body has two small hoses that come off at the front, one goes to the servo you describe, then on to the air box - that system is all complete - there's a second pipe next to it that's the problem. Aslo I have noticed there's another one that's been blocked on the rear on the throttle body !!

I'll post some pictures if I can as it's not easy to desribe ...

Cheers Gambit - the front pipe is just to the right of the oil breather pipe behind the ISV and you can't see the second hose - but it's just behind the full throttle sensor ...

Shame I can't trace the pipe from this pic but u can't see them !!!!

Blue MK2 - if you could have a look when you got some free time ( and the car ! ) it would be most apprieciated ...

I think your talking about the vacuum pipe for the MFA - that's connected to the section of pipe off the Inlet manifold you described.

Cheers for all your efforts guys !!!
