1. A method of manufacturing, comprising:
forming an integrally formed monocoque body using an additive manufacturing process, wherein the integrally formed monocoque body comprises:
a first inlet having first coupling region in communication with a first fluid line, wherein the first fluid line comprises a first inner radius that is substantially uniform along a first length of the first inlet;
a second inlet having a second coupling region in communication with a second fluid line, wherein the second fluid line comprises a second inner radius that is substantially uniform along a second length of the second inlet;
a manifold chamber in communication with the first fluid line, opposite the first coupling region, and in communication with the second fluid line, opposite the second coupling region;
an outlet having a third coupling region in communication with a third fluid line, wherein the third fluid line is in communication with the manifold chamber between the first inlet and the second inlet, and wherein the third fluid line comprises a third inner radius that is substantially uniform along a third length of the third fluid line, the outlet having a contiguous, 90 degree flow path from the manifold chamber; and
a strainer integrally formed with the outlet in the third fluid line;
inserting a sleeve-spool assembly in the manifold chamber, the sleeve-spool assembly comprising at least a spool; and
inserting a retention feature in the manifold chamber, the retention feature configured to retain the spool at one of a first position and a second position, wherein at the first position a first end of the spool blocks the first inlet, wherein at the second position a second end of the spool blocks the second inlet, and wherein at either the first position or the second position the outlet remains open.
