I'm having an issue with my fuel primer bulb collapsing and staying flat. It
s a 91 yamaha 150, While running off the main 59 gallon tank the engine idle's fine but when you throttle it's seems like it's starving for fuel and the primer bulb stay like a pancake. So I figured to run a small 6 gall aux tank and this might solve the problem NOPE, same !@#$ no luck. I'm kinda stumped I just replaced both fuel pumps because I thought it was them but no. Some one mentioned anti siphon valve but if I'm running off an 6 gal aux tank and it's doing the same thing, so does that mean the anti siphon valve isn't my problem???
I also cleaned/ checked the small round clear filter where the fuel lines attach to and that was clean as day. I'm really stumped. All Help is appreciated
Thanks CJ
