Gidday all was wondering if anyone has had this problem and can solve it for me.. I had a problem with my injector pump on my 60 2H leaking so i fixed that but when i started it No. 1 and Two injector lines really thumping hard and a whistling sound can't track down from where..couldn't find problem so i took a pump off my other 60 which was running well..put it in and same prob.. Got me baffled, can anyone help?? Cheers
