What you have is a post LAC 3833 , AF 63-7767 fuel system . On this system the SPR shares plumbing with the dump system.Try this: allow extra time for the SPR to drain prior to closing the valves & shutting down the SPR.The fuel that you see is SPR fuel accumulating in low spots , then coming out during taxi & takeoff. This was considered major when the FY 63's went into service , but troops learned how best to refuel then the problem subsided.

58-0754 LM3553 S3AGA
59-1537 LM3589 S3AGB
61-0962 LM3647 S3AGC
61-2640 LM3676 S3AGD
These are all of C-130 aircraft. .repeatedly it's occurred means fuel flow through dump must when taxing on ground.
so can we solve the problem by SPR draining proproperly?As refuelling and dump plumbing is same.but confused that dump valve for individual is not available?

SPR & Dump plumbing sharing do not apply to "B" models. "B" models have separate SPR & Dump system , very simple .Question for you 1. Are the AUX Tanks full when this fuel spill happens ? 2. Are the Aux Tank Pumps on during Taxi ? 3 Does it happen on all your airplanes ? Please review the fuel system for "B" models in the flight manual ,TO 1C-130B-1.
