All of a sudden the gas fumes on my boat have become extremely noticable and unbearable and a serious fire hazard.

It currently has maybe 10 gallons in each tank and I believe the problem is coming from my fuel filler hoses and vent hoses based upon what I have read in thusforum and others.

I've also been told that changing them out is a fairly easy task that can be done myself.

Does anyone know if there are any step by step DIY directions or videos of photographs showing this being done or can anyone give me an idea of where to order these hoses and how to start and any sage advice they have accumulated along the way

Thanks in advance for your help
