I just recieved a map sensor from Jason Cromer, I told him to order me a map sensor for a 94lt1 etc. I recieved it in the mail the other day. I am piecing back my new motor buying all new sensors,etc. Well I tried to install the map sensor today and realize that the hole on the top where the map sensor goes in the sensor tube on the bottom is way too small for the hole. My ? is, is there a o ring or something that helps it fit the hole better, or do I have a map sensor for another gm car. I know if I install it the way it is there would be a vacum leek.

Thanks Mark

 

You need to reuse the rubber fitting that was on the origional MAP sensor.

 

That is what I thought, but damn I threw it away. Where could I get one?

 

Hmm, maybe a dealarship or parts shop.

 

The part number for the MAP sensor seal is listed on my website. Click p/n link in sig.
