hi, i bought a map defensor my question is.. i know u replace this with ur map sensor but where do u hook the hose to? anyone know? thx

 

show us a pic of what you have

 

wtf is a map defensor? This term is new to me...pics please!

 

to the OP: This is a very bad way to run a boosted car, FMU and checkvalve setups are nothing but band-aids, in other words you are asking for trouble. I suggest using a 3bar map sensor and a chipped and tuned ECU.

Anyway heres the info you're looking for:
You hook the map sensor up to the end of the tube.

Hook the metal plate up to where your factor MAP sensor mounts, then hook the end of the tube coming off that machined plate to your map sensor and mount the map sensor somewhere (such as the firewall).

For the others:

A map defensor is nothing more than a Missing Link aka check valve.

The Inline PRO map defensor completely eliminates map sensor trouble codes caused by boost pressure.
This is a must device for users utilizing factory ECUs.
