vacuum routing ? for map and brake booster on new manifold
Can I run the brake booster and map sensor off the same vacum port or do they have to be seperate? Im installing the weiand 7525 and it doesnt have the factory brake booster port so Im going to use the only port it has at the rear of the manifold. Can the map sensor be plugged into one of ports on the TB or does it need some special placement of the port?
thx

Run the MAP sensor from the rear port on the TB.

IIRC - there's a brake booster vacuum port on the TBI unit - all the TBI cars connect the brake booster to that do they not?

no there is no booster port on the TB its a seperate fitting on the manifold.
Thank you I did just what you said about putting the map on the rear TB port, it made sense when I was looking at it before I checked back and read this.
