the smallest M12x1.25 I can find is 20mm length. Is this too long to cause flow issues? what did you guys use in terms of length?

if you cut down a bolt, run a die over the threads. You don't want a sharp or bent thread to tear up your fuel rail.

if you dont have a die of the right size, you can put a nut on the bolt, cut the bolt and file the edges, then back the nut off.

ok thanks guys, 10-12 mm looks about right. Nobody sells a simple block off plate/bolt for this yet?
