I had the fuel pump "short jumper harness" melt down on my x9, as described by others in this thread:

I got a new harness, cleaned up the female pump side of the connection as best I could, and plugged in the new harness. The boat started right up.

The question is, however, should that connection be getting warm at all? I ran the boat for a bit, and the Packard connector on the top of the pump was a little warm. I'm wondering if this is from the increased resistance of the pump's connector, or maybe the pump is working quite hard, drawing a lot of current and I should be getting ready for my third fuel pump failure. My fuel level was lower that I usually keep it, at around 10 gallons remaining.

Opinions? Experiences?

I don't have this year fuel system - but I don't think any electrical connection near the fuel cell should be getting warm just my opinion.

Decided to take the fuel pump canister out and have a look since it was still it bit too warm for my liking. Here's the bottom side of the connector:

Screw that mess. That's completely wrong. Might be a bit of a knee jerk reaction on my part but I'd replace the entire unit and strip out any usable parts for spares. I wouldn't even start it up again with that as part of the fuel system.

I had a boat burn on me while out in the middle of the Detroit river. Believe me you don't want a similar experience. Whatever the cost of the new unit, it will be dirt cheap in comparison to the possible alternative.

Have you measured the current draw of the pump? This was a condition ive seen on a lot of late 90's well in to the 2K's chevy/gmc trucks and SUV's. In these cases, the pump's current draw was excessive, resulting in the melting connectors.

Turn the plug over, so you can show where it's supposed to slide onto the stainless tab with the bend near the end. Then, slide it onto the tab and look at the pins vs where the plug went on- it looks like the plug went on physically, but it looks like it was turned 90 degrees to the left, which means it SHOULD have had a problem. Who installed this pump?
