Im trying to install my rc440's in my b18a and they wouldnt fit in the stock gromits. So i tried to bore them out a little with sandpaper rolled up...it works ok but its takes WAY too long. How can i do it faster without a damn dremel tool? Did your rc's fit in the stock gromits? Thanks

I took an exacto knife and cut a little off of the inside of the grommets. Seemed to work fine but you don't need to take off very much.

 

I pitched my old grommits, 440's fit like a glove, no leaks...

Your injectors should allready come w/it's own grommit though...
