Routing Oil Hoses Behind Engine Mount

[Piper J3]

I remember a change for routing oil hoses behind engine mount but can't find documentation. I'd like to route both hoses from oil tank between standoff and rear ring on main engine mount.

Drawing below shows one oil hose between the mounts and one hose behind.

I'm also searching for how oil pressure hose should be routed to the sensor mounted on the firewall.

Any help appreciated...
