Author Topic:   Fuel primimg bulb noise

The previous owner of my 1994 Rage 14 installed a priming bulb on the fuel line. When I use it to prime the fuel prior to startup, it makes a fairly loud whistling noise until it hardens up. The priming bulb on the vro oil line is completely silent.

Is this normal or is it an indication of an air leak in the line?

The reason I ask is that I've read elsewhere on this board that air leaks in the fuel line can contribute to excess smoking from the TurboJet engine that I have and I want to make sure I am doing everything I can to reduce the smoking.

Come on fellas, No one here knows if their fuel priming bulb makes noise when it's squeezed?

I don't have a Rage, but I do have a Revenge, which starts and ends with the same letters! I've never heard any of my primer bulbs "whistle" on the four boats I've had. I would replace the primer bulb , before I did anything else, they are cheap, but get the Mercury ones they are better then aftermarket, and try and install it with the arrow pointing up, the check valve works easier in that postion........Jack

My '95 Rage has a primer pump with a center priming button mounted on the "engine room wall", it makes a noise if the engine has not been running for months and really needs priming. As the fuel pressure increases the noise stops and I can feel a lot of resistance in the button.
I am new to outboards but it seems resonable that as the pump is forcing fuel in to hoses that had air in them (hence the need to prime) that you would hear the fluid movement. If the bulb holds pressure after starting I would think that you do not have an air leak. JMH has an excellent article in the reference section.

ps: I should add mine makes a gurgle sound. If you think the whistle is coming from a connection, take the head off a stethoscope, or even a section of tubing and hold it next to each connector while priming.
