Re: Splitting the fuel line for a main motor and a kicker
I have run split lines without valves or anything else for 17-18 years. No problems. I run them out of a spin on fuel water separator. Not to be a wise guy, but please check that the bulb is actually creating suction on the end you want it to. Out the end of it on your thumb, then squeeze it with the other hand, If it doesn't try to latch onto your thumb, there is an issue. If it tries to blow your thumb off, then the bulb is going the wrong direction.
