so i have a lil problem.

what end do i need to machine to allow these injectors to fit the stock fuel rails?

cant i just cut off the yellow cap at the bottom? me gets dremmel out.

 

I cut the yellow cap off, and had to find an O-ring that fit the injector tight, and fit the bore tight (stock one is too big for the injector)

Then the top needs to be ground to fit into the rail further and needs to use the stock o-ring. Basically grinding the grey plastic portion down enough to recess into the rail.

 

ah ok.
