Default Manifold Pressure Sensor (MAP) vacuum line

broke my vacuum line running from the map sensor to the throttle body while messing with my electrical mess, oops.

the thing is super brittle and ive replaced all the other vacuum lines any way so im not too bummed, trouble is i cant find the thing for sale. also would like to replace the rubber grommet it goes into on the throttle body.

anybody know where i can get them?

searched for a good while on rockauto and google and on here, no luck

Help a brother out.

i replaced most of my plastic vacuum line with a small rubber hose. i left the grommet on the TB. looked like something that shouldnt be messed with, to me at least.

ah man, im far to curios to leave things alone. if i dont know what it is i got to poke and prod it till i figure it out. most of the time it works out sometimes i get myself into trouble.

in this case it worked out...
not sure what the top port (of the 2) goes to cuz it was broke off flush and cant find anything in my vacuum schematics. i plugged it up with a rubber plug i fashioned with a razor blade.
for the port that runs to the MAP., i lubed up and stuffed an old vacuum fitting left over from replacing my vacuum harness. works pretty good actually.

So problem solved, on to the next one.
