This is the disassembled Carter pump that came out of my boat. Makes you wonder if there is enough heat to melt the nylon around the + and - contacts, why the bomb doesn't go off. This pump was frozen and I wanted to know what seized it, there was no trash in the pump itself as it is still free, the nylon melted to the contacts.
I used an ORiley pump E2044 for replacement. Attaching it to the plastic fuel line is an PIA but with a little time it can be done. I have 4 hours on pump now and it works fine and pressure at the fuel rail is in spec with MC manual.
Hope this helps others as I cant believe with a pump that is cooled by fuel it pumps can get this hot and not be a manufacture issue.

Nice work. It does look like the problem might be specific to this carter pump. Lets hope our replacements work out a little better.
It makes me feel better not putting that same pump back into my boat, especially at $500 a pop!

Now I would love to see someone do a step-by-step "how to" for replacing this pump. Pictures would be great too.

Same dead fuel pump problem

Once completed, it started right up and ran fine.

The specifics: 2002 X-30, LTR 330HP, Carter pump #71-333S - CGB 98-002. For what it's worth, the NEW Mastercraft part number the guy gave me was 155193.

Thanks again for all the info provided in these posts
I have a 2003 Xstar with 350 MCX, and had the died while idleing thing happen to me this weekend. My pump has the same 71-333s carter numbers that you have, and my pump MC part number is 155193 according the chart that boofer referenced in another thread (http://207.170.215.108/awweblive/Aww...IX%2099-07.pdf).
Did you use the ACDelco EP356 pump that was mentioned earlier in this thread. So far every one but you has had a different MC part number according to boofers chart than what my boat was calling for. I am just trying to confirm that the EP356 pump works in my fuel module also. Thanks for your help

I have not had the time yet to dismantle my old pump and do the research. I hope to find a definitive replacement alternative. I am also going to try to come up with a modified USCG compliant system.

Boofer,
Great job with the pics, I just took my pump module out today and was going to take pictures, but it looks like you have it covered. Thanks for your hard work, it has helped me tremendously in mustering the courage to take the pump out. I have it out and taken apart. I am now trying to figure out if the EP 356 fuel pump is going to work in my module. My boat is a 2003 X-star with 350 MCX, the fuel pump module MC part no. is 155193, the actual pump has 323 and 3081A (or 3091A, can't tell which) Carter on the side of the pump. The fuel system has a high pressure line to the injector manifold as well as a return line back to the pump plate, which is a little different from your single line pump. The pump plate has Carter 71-333s and CGB 98-002, the same as Jontaylors. If you or anybody else knows if the EP 356 or equivalent will fit the module in my boat, I would appreciate any help. My pump is already out, but if anybody needs any pictures of the MC part #155193 pump module which is my 03 X-star after it is taken apart, I would be glad to post them. Thanks again for the great work......

No problem flame. Thanks for the support. I also appreciate the information from your pump module. I hope to get to the dissection soon. Been working on an A/C leak in my car. It was a royal pain.

Your system probably has a regulator mounted to the fuel rail. That would explain the return line. My system is a "returnless" system. The regulator is on top of the fuel module. Any excess fuel from the regulating process is dumped straight back into the tank.
