I've developed an issue with my fuel system where it's losing prime. You can press the plunger crack the bleeder screw to get the air out and it'll be firm for about 3 seconds then it's soft again. Also it does not matter on fuel level. It does it full or empty. I've also not noticed any fuel leaks. I re-sealed the filter head. Replaced the bleeder screw with an aluminum one. Then put on the sinister cat fuel filter adapter in attempt to see if it was the WIF sensor. Then replaced the entire filter head and still the problem persists. Any insight would be great. Thanks in advance!
