2002 x-star LTR 330 fuel system questions

Hi All,

Boat is new to me, has been runnning great for a month. The fuel gauge is wacky though and I think I ran it dry. Idling around the lake tonight and it ran rough for a second, then stalled. Turned over just fine, then stalled. My neighbor came over with a can of gas. Filled it up, turned over fine, ran for a minute, then stalled.

Wondering if it pulled sludge from the bottom of my tank or if the neighbor's gas was bad. Continues to turn over easy, sometimes runs for a minute but then stalls. Replacing the fuel filter seems like the right place to start, but I have no idea where it is. Anyone know where I can find it and how to access it?

Thanks for any help!

Its either the RTP (310 hp) or the LTR (330 hp) engine. Unless it was replaced with a MCX
(350 hp) engine sometime in its life?

Yes, thanks for clarifying. It's the LTR engine.

Cool, same motor as mine, (LTR) I'll be at my boat tommorow, and I'll look closely around the engine, as I haven't replaced mine yet to date. But I am sure that someone will be along very shortly who has replaced the fuel filter on that engine at one time...

I would check fuel pressure after it stalls.
It is common for the fuel pump to go especially after being run dry.

Probably the pump. As indicated above check fuel pressure on the rail and verify that pump is getting power by checking for 12volts at the plug on top of the fuel pump unit if no pressure to rule out electrical issue. I have read that a few had problems with the wiring connector corroding.

Fuel pump, almost certainly.

Thanks all. Can anyone confirm the Napa part number for the fuel pump replacement? I'm going to tackle it tomorrow.
