A fitting for attaching to double wall tubes includes a body, a fitting center port, an outer seal, a tube connection, a pad connection, an inner seal, a groove, and a diagnostic port. The body has a first surface on a first side of the body and a second surface on a second side of the body. The fitting center port extends through the body for passing a primary fluid flow. The tube connection is on the first side of the fitting, and includes an inner connection and an outer connection. The groove is in the second surface surrounding the inner seal and the groove is configured to receive an outer seal. The diagnostic port is in the second surface for transferring a collected fluid through the body to the outer connection.

1. A fitting for attaching to double wall tubes, the fitting comprising: a body having a first surface on a first side of the body and a second surface on a second side of the body;a fitting center port extending through the body for passing a primary fluid flow;a tube connection on the first side of the body, the connection comprising: an inner connection protruding from the first surface, wherein the inner connection surrounds the center port for attaching an inner tube; andan outer connection protruding from the first surface, wherein the outer connection surrounds the inner connection for attaching an outer tube;a pad connection extending from the second surface of the body, wherein the pad connection surrounds the center port and connects to a mounting pad;an inner seal surrounding the pad connection and adjacent to the second surface of the body;a groove in the second surface surrounding the inner seal, wherein the groove is configured to receive an outer seal; anda diagnostic port in the second surface for transferring a collected fluid through the body to the outer connection;wherein the inner seal passes over part of the diagnostic port. 2. The fitting of claim 1 and further comprising a plurality of fitting mounts spaced radially away from the center port on the second side of the body for receiving fasteners, wherein the outer seal circumscribes the fitting mounts. 3. The fitting of claim 1 and further comprising a trench in the second surface of the body located between the diagnostic port and the pad connection. 4. The fitting of claim 1, wherein the fitting has a shape of a triangular prism with rounded corners. 5. The fitting of claim 1, wherein the fitting body is formed of a single piece. 6. The fitting of claim 1, wherein the fitting material is one of a titanium alloy, a stainless steel alloy, aluminum alloy, or a nickel alloy. 7. The fitting of claim 1, wherein the diagnostic port has a hydraulic diameter sized so that surface tension and capillary forces created by the diagnostic port acting on a leaked fluid are overcome by flow of an amount of leaked fluid. 8. The fitting of claim 1, wherein the inner seal and outer seal are c type seals. 9. A method of distributing leaked fluid for visual leak detection, comprising: passing a pressurized fluid from an inner tube through the fitting of claim 1;collecting a leaked fluid at the diagnostic port on the second side of the fitting body;passing the leaked fluid from the diagnostic port to an outer tube connected to the first side of the fitting body; andtransmitting the leaked fluid to a location for visual detection. 10. The method of claim 9, wherein the leaked fluid is transmitted using only gravity as a motivating force to the location for visual detection. 11. The method of claim 10, wherein the visual detecting location is at a cowl of a turbine engine. 12. The method of claim 9, wherein the pressurized fluid is leaked around the inner seal on the second side of the fitting body. 13. The method of claim 9, wherein the pressurized fluid is leaked around the outer seal on the second side of the fitting body. 14. A double wall tube assembly for distributing a pressurized fluid, the assembly comprising: a fitting for attaching to double wall tubes, the fitting comprising: a body having a first surface on a first side of the body and a second surface on a second side of the body;a fitting center port extending through the body for passing a primary fluid flow;a tube connection on the first side of the body, the connection comprising: an inner connection protruding from the first surface and surrounding the center port; andan outer connection protruding from the first surface and surrounding the inner connection;a pad connection extending from the second surface of the body surrounding the center port;an inner seal surrounding the pad connection adjacent to the second surface of the body;a groove in the second surface surrounding the inner seal, wherein the groove is configured to receive an outer seal; anda diagnostic port in the second surface for transferring a collected fluid through the body to the outer connection;wherein the inner seal passes over part of the diagnostic port;an inner tube connected to the inner connection;an outer tube connected to the outer connection and surrounding the inner tube; anda mounting pad for mounting to the second surface of the body, wherein the mounting pad comprises a fluid inlet for receiving a primary fluid flow from the fitting. 15. The double wall tube assembly of claim 14 and further comprising a heat shield surrounding the fitting. 16. The double wall tube assembly of claim 14 and further comprising a plurality of fasteners, and a plurality of fitting mounts spaced radially away from the center port on the second side of the body for receiving the fasteners and for mounting the fitting to the mounting pad. 17. The double wall tube assembly of claim 14, wherein the inner seal and the outer seal are c type seals. 18. The double wall tube assembly of claim 14 and further comprising a trench in the second surface of the body between the diagnostic port and the pad connection.
