I removed the fuel module from the tank. I tried to blow through the barb on the regulator with the it still assembled and could blow air through it. That told me I had a leak between the regulator and the fuel pump itself. When I disassembled the module, I inspected the hose between the regulator and the fuel pump for any tear or slice, etc. I removed the fuel pump and closely compared it with the original carter pump. On the air tech the barb is different. It has a 5/16 nipple at the end of the barb but below that it has a shoulder about a 1/4 in long and a 1/4 in outside diameter. (The Carter pump was 5/16 all the way down the barb.) When I installed the pump this is where I clamped the hose down. To fix the problem I added another clamp to the hose to have two clamping points. One directly over the 5/16 OD and one over the 1/4 OD shoulder. This alleviated the problem. So if you go with the Airtech E2044 from Autozone for $90.00 be cautious when installing the hose onto the barb. I have an MCX in a 2006 X-Star. According to my fuel pressure guage at Idle I'm running 69 psi, now when I turn the key off the pressure drops to about 60 psi instead of 0. This thread saved me about $400 or more in just parts.

Thank you very much for this thread. I have an 07 X1 that just had a fuel pump go out this week. Right now I am still under warranty so I let the dealer fix it, but this information is very useful for when I do get off warranty.

Thanks to everyone who has gone before me on this fuel pump issue. I just bought an X-2 from a dealer and BAM, 4 hours into my new ride the fuel pump went out. I replaced the pump with the suggestions from this post and am back on the water within 1 day.

Props to the dealer, Bay Area Watersports for offering to overnight me one at cost. I couldn't wait and got it fixed on my own.

I think all the modules are the same. They are "expandable" for different size tanks.
