This website has truly been a savior and it is amazing how knowledgeable everyone is. As you could tell from my other post I am kind of learning as I go with a used boat I bought last season. My latest problem is when I run my Volvo gxi 5.0 3869255 the engine starts right up then runs for 2-3 mins then I start to hear a loud pitch squeel and it shuts off but can be restarted without a problem. The high pressure fuel pump is hot and I believe it is where the noise is coming from. Should I just assume it needs to be replaced. As always thank you so much for any insight
