| its the new ULSD fuel. it has no lubrication like the old fuel did. it will stop eventually. it is your injection pump making all the noise. the fuel goes into the pump before through it and to the injectors to lubricate the pump and the new fuel does not have the viscosity and lubrication that the fuel last year did. Get some BG Diesel Lubricant additive its like 9 bucks for enough to treat 120 or so gallons. |
