Map Sensor Vacuum Source ?

[Eagle-Mark]

Is there a vacuum source that would be adequate for the map sensor on the throttle body itself?

I'm trying to mount the map sensor under the air cleaner with the vacuum line straight down. Thought it would be a good place?

I just found this picture over on Snufulupagus site, he has so many pictures of TBI. There is a link on the links page, check it out!

MAP sensor

There is a port on the bck of the throttle body that is the production location for theMAP vacuum source. Other than that I believe that the far left lower port on the front is manifold vacuum and should be used.

This MUST be manifold vacuum, it MUST be leak free and MUST not have a long length of hose and/or any kinks in the hose.

This is the brain of the unit, speed density, this is the density half of the equation.
