It appears that on the aft end it rises up above the pushrod. Is there enough slack to reverse that? I.e.: have it curve down and slightly outboard of the pushrod.
-a doubler on the belly skin
-adel clamp the oil line to the belly through doubler.
-if not enough slack, make a “z” bracket out of 1/16” angle to stand your clamp up off the floor and hold the oil line outboard of the pushrod.
Good luck!!
