Default Map sensor in FAST intake

I pulled the map sensor off my stock manifold and went to put it in the fast and it goes in fine but it's kinda loose. Is there a new grommet i can buy or will it be fine. it stays in ok but i dont know how much pressure builds up in there and i dont want it to blow out or anything if it is possible. Any ideas on what i need to do? thanks

You would have to buy a new map sensor to get the gromet (about $35).

They are not the tightest fitting gromest to begin with. I did my swap I used the one from my stock intake and have not had a problem. I would keep a eye on it and replace if you need to.

You can buy a new grommet for like $5 at the stealership, it will stay in a lot better. The new FAST intakes are coming with a "revised" MAP hole, my friend just put one on.

I don't remember seeing a J on there. But the sensor fit into it great w/ the old grommet.

I bought a new seal for the MAP when I put my intake on. I don't think it helped much at all so I used some rtv also. Made it a lot better. Just make sure it dries before you put the intake on.

I just pulled it out of the old manifold, cleaned the grommet, and then stuck it in the FAST with no problems. It felt snug to me.
