I was just reading this and saw the part about poor Fore hat gasket. I got the Fore hat for twin GT pumps and it said to reuse the OEM gasket (it did not come with one) and I had to cut and shorten the little stubs that stick out as they don't got as deep into the Fore hat as the oem hat. I have not had any leaks in over a year now. Knock on gas tank
