Singapore Air Force is flying several KC-130B\'s with out the external tanks. Being a shadow guy it does look weird... D

From what I know, the shadow off-load valve was done with the HAR pods since it was wired that way long before the UARRSI mod (back when we called em \"Humpies\"). FTD was a long time ago but... On shadows the re/de-fuel manifold is used to deliver fuel to the HAR pods. What good would it do to drain the entire manifold after a refuel, go upstairs, put fuel to the pods only to fill it up again?... This way the lower portion of the SPR that\'s exposed to the wheelwell is drained leaving fuel in the upper portion of the manifold for HAR. You can tell when the off-load is closed on shadows, while draining after a re-fuel the SPR poppet valve sucks air in while it drains, normal herks don\'t due to air being let in by a check valve up in the flap-wells (the ones that leak in cold weather). Hope this helps. Cheers.
