Well lucky for me I have both size rails in my hand
A DSM OEM 1G fuel rail is NOT the same size as a -10AN
I got here a -10 rail and a OEM rail and not even close to being the same size
On a OEM rail the hole is 15mm but if you look inside the rail its only 14mm beacuse as it comes towards the end of the rail it has a lip of 1mm.
As for a -10AN rail its 19.5mm
OEM= 14mm
-10AN= 19.5
The exterior dimension of the stock rail is 1mm larger than the interior diameter of a -10 rail
