The systems and methods can be used for tufting different types of yarns, such as turf yarns, staple yarns, or yarns having a denier greater than 5000. A system can have a pair of guides and a clevis movable between the pair of guides. The clevis defines an opening therethrough. The clevis and pair of guides are configured to engage a yarn to so that the yarn contacts only exterior surfaces of the pair of guides. ## Claims ### Claim 1 A system for use within a hollow needle tufting machine, comprising: a pair of guides; and a clevis movable between the pair of guides, wherein the clevis defines an opening therethrough, wherein, in a use orientation, the clevis and pair of guides are configured to engage a yarn so that the yarn contacts only exterior surfaces of the pair of guides. ### Claim 2 (depends on 1) The system of claim 1, further comprising a yarn extending through the opening through the clevis, wherein the yarn contacts only exterior surfaces of the pair of guides. ### Claim 3 (depends on 1) The system of claim 1, wherein the pair of guides comprise a plurality of openings therethrough, wherein: in a second use orientation different from the first use orientation, the pair of guides are configured to receive yarn through the plurality of openings. ### Claim 4 (depends on 1) The system of claim 1, wherein each guide of the pair of guides comprises a recess formed on a side of the respective guide. ### Claim 5 (depends on 2) The system of claim 2, wherein the yarn contacts respective lower sides of the pair of guides. ### Claim 6 (depends on 1) The system of claim 1, wherein the pair of guides do not include holes configured to receive yarns below respective midlines of the pair of guides. ### Claim 7 (depends on 1) A method of using the system of claim 1, wherein the system is integrated within a hollow needle tufting machine, the method comprising: tufting, by the hollow needle tufting machine, the yarn through a backing, wherein the method does not comprise applying, using a pressure foot injector, a pressure of greater than 10 psi. ### Claim 8 (depends on 7) The method of claim 7, wherein the method does not comprise applying any air pressure via the pressure foot injector. ### Claim 9 (depends on 7) The method of claim 7, wherein the yarn is a turf yarn. ### Claim 10 (depends on 7) The method of claim 7, wherein the hollow needle tufting machine has a plurality of needles, wherein sequential needles of the plurality of needles are spaced from ½ inch to 2 inches. ### Claim 11 (depends on 7) The method of claim 7, wherein the hollow needle tufting machine has only one single row of needles. ### Claim 12 (depends on 1) A method of using the system of claim 1, wherein the system is integrated within a hollow needle tufting machine, the method comprising: applying a first pressure of above 90 psig for feeding or tufting the yarn; and applying a pressure to a needle injector, wherein the pressure to the needle injector is above 90 psig. ### Claim 13 (depends on 12) The method of claim 12, further comprising applying a second pressure for holding the yarn, wherein the second pressure is lower than the first pressure. ### Claim 14 (depends on 13) The method of claim 13, wherein the second pressure is above 70 psig. ### Claim 15 (depends on 12) The method of claim 12, further comprising applying the first pressure for holding the yarn. ### Claim 16 (depends on 10) The method of claim 10, wherein the yarn is a turf yarn. ### Claim 17 (depends on 12) The method of claim 12, further comprising feeding the yarn through a respective opening of a plurality of openings through a manifold bar, wherein each opening extends along an axis that meets a vertical axis at an angle of at least 14 degrees. ### Claim 18 The method of aspect 17, wherein the each opening extends along an axis that meets a vertical axis at an angle of from about 14 degrees to about 20 degrees. ### Claim 19 (depends on 1) A hollow needle tufting machine comprising the system claim 1. ### Claim 20 (depends on 19) The hollow needle tufting machine of claim 19, further comprising: a frame, wherein the pair of guides are coupled to the frame, wherein the clevis is movably coupled to the frame; a manifold bar; a needle mounting bar; a plurality of needles mounted to the needle mounting bar; and a plurality of yarn delivery tubes extending from the manifold bar to the needle mounting bar, wherein the yarn extends through the clevis, into the manifold bar, through a yarn delivery tube of the plurality of yarn delivery tubes.
