Need to move the firewall mounted oil cooler left 5/8" to increase spacing with the mechanical fuel pump exit port. Fabricate a new and longer aluminum angle that mounts to the firewall to support the oil cooler aft mount tabs. This is a tedious location for mounting because the engine mount hinders access to the attaching hardware. Ultimately persevered and the cooler is hopefully mounted with sufficient clearance with the fuel pump. Right picture shows before moving and the left picture after moving oil cooler.
