Just installed mechanical fuel pumps on 500 efis
I have the first gen. 500 efis with only the electric high pres. Pump on the cool fuel. And it has vapor locked a few times so I installed the next gen raw water pump with a mechanical fuel pump. All of my other boats have had both pumps and never vapor locked . So we will see its hot as hell!!!!!
