i forgot which this hose goes to. so could somebody with an EF let me know ASAP

the hose in question is the one going "towards us"
the t-piece connects to the other part of the map sensor, so its not that



thanks

IIRC, Normally there is the one hose from the MAP sensor that goes to the port on the BBM across from the LHS strut tower. The other closest possible point is the vaccy tree near the fuel reg.
Looks like your vaccy line setup has been modded. There should be a rubber junction block nearby which handles the ventilation system vacuum, switching valve for BBM - the vaccuum source for this comes off that tree near the fuel reg.

There is another vaccy tree below the TB, but that is usually for the PCV and carbon canister.

OH YES thankyou... just remembered.. my BBM butterfly actuator was modified and used that part... but now i removed butterflys so i dont need that anymore
