AMPTestFE Posted January 19, 2016 Share Posted January 19, 2016 It sounds as though you have verified power to the refuel valve, right? If so, have you verified the valve operates? Quote Link to comment Share on other sites More sharing options...

Do all the other tanks on the right wing take fuel? Quote Link to comment Share on other sites More sharing options...
hehe Posted January 19, 2016 Share Posted January 19, 2016 MC-130P, MC-130H, AC-130 or EC-130H? I'm going to assume the refuel valve you are saying you checked is the uarssi fuel valve which would be opening if all other tanks are receiving fuel. Have you simulated a tanker? (Refuel through the uarrsi) to see if you can actually put fuel in the tank Quote Link to comment Share on other sites More sharing options...
tinyclark Posted January 20, 2016 Share Posted January 20, 2016 The valve in the #4 tank is not working. There is no other item that it could be. Was the ground checked for the valve checked? Quote Link to comment Share on other sites More sharing options...
cfknock Posted May 22, 2016 Share Posted May 22, 2016 I had this happen to me once before, fueling a primary asset. Turns out the precheck switches on the SPR were on the outs. The switch being made, left the system in a simulated "Tank Full" position and wouldn't take any fuel. If you haven't figured this one out yet, it might be a place to look.

AMPTestFE Posted May 30, 2016 Share Posted May 30, 2016 Had this happen to me on my first deployment...no matter what I did, how many times I cycled the switches, main tank wouldn't accept fuel. Had to over the wing refuel. Got back to the FOB, it worked just fine. Quote Link to comment Share on other sites More sharing options...
