Looking for fuel system diagram for 2021 Bennington

[DiamondDave952]

Hello. My primer bulb normally is stiff when squeezed for the last 5 years of ownership. This past Spring, I noticed the primer bulb wasn't stiff and the motor still performed as normal. Thinking the primer bulb had gone bad, I bought a new OEM primer bulb from my Bennington service center with the intent of replacing it in the Fall. Well, today is the day I replaced my primer bulb with high hopes the new bulb will be stiff when squeezed. Unfortunately, that was not the case. Does anyone have a diagram showing where all the hoses are connected from the internal fuel tank to the engine? Trying to troubleshoot the issue before storing it away for the Winter. Thanks!

Do not have a diagram but I can describe the fuel flow path. The fuel flows from the tank to the filter and then on to the squeeze bulb and finally to the motor that contains the fuel pump. It is probable the bulb has collapsed do to plugged fuel filter.

Does the primer bulb need to be primed? By that I mean, should I have connected the inlet to the primer bulk and squeezed it to get fuel to exit the outlet side before connecting to the engine fuel line? When I squeeze the bulb I can hear fuel moving in the tank but feels like nothing is getting to the bulb. Is it possible I have an air lock in the hose?

Yes you will need to work with the basic design of the primer bulb to get fuel up into the bulb. The bulb has a free floating check ball on each end. When priming make sure you are holding the bulb outlet somewhat upward so the balls can rest on the seats. For the benefit of others the outlet is identified with an arrow. I suppose you could squeeze the bulb before the outlet is connected just to see the fuel squirt out. Once the outlet is connected and the bulb is pumped it should feel full and hard.
