    Well, I am pleased to see all of this "progress." I want to caution all of you about using aftermarket parts. Despite the fact that these pumps seem to be fitting the bill, PLEASE be careful. I opted for the $400+ MC module because I was not comfortable using a part that someone on a message board says will work without any hard background information. The fuel pump is a critical item on a $40k+ boat. It is not something that you want to ad lib. Having made my disclaimer, I have some new information.

    I plan on starting a new post soon. I dismantled my old module and took a buttload of pictures. I also went to AutoZone, Pep Boys, and Advance to attempt to find a cross reference. At Pep Boys they cross referenced the EP356 with a Carter P74122. I did not have the module number with me (71-342S). When I got home I called them with this number and they did not have a cross reference. They tried "P71342" and a couple of other variations. The pump "looked" similar, but so do most in tank fuel pumps. This is another caution point! Just because they look alike, they may not be alike.

    I am going to go to a Federated Auto Parts store next week. I spoke with a guy there that was sure that he could help me find a valid cross reference. He said that he had a great deal of experience (18 years) with this sort of thing (proprietary parts) and superseded parts.

    Now, as soon as I get the time, I will begin my other post. First impressions with my "evaluation" lead to either a bad hose (from the fuel pump to the regulator) and/or a faulty pump. Apparently, Carter had to redesign the fuel pumps they sold to GM because of a high failure rate. And, the hose I mentioned is different on my new module (totally different).
    Common sense is the least common of all the senses.

      I have to thank all of you for this information. I have a 2002 X-star with the same set up and baught the new e2044 and it worked excatly the same as the original which you might think was a good thing but not so fast. The original pump wasn't bad, even after a trip to the dealer I was told the fuel pump was bad and needed to replace the whole module, as we all know $450.00. So I took the advice off this thread and baught the e2044 and installed it, same issue loss of power and bogg down beyond half throttle. After futher inspection notice that their peace of crap fuel line was kinking after I reassembled everthing. I went to advanced auto and baught fuel line for $1.25 installed it and presto magico, she run better than she ever did. I wonder how many people out there have had loss of fuel preassure and got burnt from the dealer for $450.00 for what could possibly been $1.26 fuel line. I think there are many problems with Carters set up, even if Master Craft or the dealers refuse to help us, post like this will.

        boofer, I have been in the parts buisness for 18 years myself and one thing I lurned is that some manufactors, exspecialy pump manufactures, use part numbers like serial number, they don't alway's cross from different aplications. Some one at Carter would have to do that ( could luck with that) because the numbers themself might indicate the application ie. automotive, aviation, marine, so it might not be even possible for anyone else. If you have an electrical component in a fuel system I would think that the standards must be pretty strick, no matter what equipment it might be in. So as we often do in my line of work is, if the voltage , psi, gph match and it fits in the supports, it will work. I now know from my own experince with the e2044 installed in my boat, I can say, they can stick that $450.00 right up there butt. No expert just my 2 cents. By the way thank you for your efforts in getting the facts can't wait to here what you find out. Keep up the good work.

          I know what you mean BearCreek. I am going to do my best. Sometimes, it is a case of talking to the right person. And that is usually just a matter of luck.

          I caution you though on the fuel hose that you bought. None of the stores around here carried in tank fuel hose. They carried "fuel injection" hose which is used outside of the tank. The correct designation for in tank (submersible) fuel hose is SAE 30R10.

          The short span of hose on my old module was kinked. It was kinked to the point that I would estimate that it was only good for 1/2 of its capacity. The new module had a completely different looking hose. It is clear and corrugated unlike the smooth black one in the old module.

          I am real curious if GM had a recall relating to the Carter pumps. I cannot find anything pertaining to one. If anyone knows, please speak up.

          Odds are that a pump with the same specs will suffice safely. I believe that engine nut (Indmar employee) somewhat verified that the EP356 fits the bill. But, I want to help give people like myself (anal), some peace of mind.

            I agree with you on most points but I think if you want absolute peace of mind you better stick to the OEM part.
            I think you will find that as the info is proprietary to MC and they choose not to disclose it, we will have to go the trial and error route. Now we are obviously not just flying by the seat of our pants here either.
            What are your main concerns as they pertain to the pump? Capacity? pressure? because we have confirmed that these aftermarket pumps are sufficient in both regards.
            Anyway I urge everyone to check the gallons per hour and pressure of the replacement parts before they go in. If not just for peace of mind more than anything else.
            Boofer good luck with your quest and thanks for all info you have provided up to this point.

              mine btw was $60...and that E2044 is a another direct cross number

              My replacement pump looked almost identical to the e2044 you have on the right side of the pic. Screen and everything. I used the NAPA part but it looked just like that.

              I would go with that pump. DId you get the specs on either? GPH and/or PSI? Just call them back and ask for them, they should be able to tell you.
              Sorry it took so long to get back to you, but I decided to take a couple of extra days at the lake, and just got back home. As you can probably tell from the other post by now, the E2044 pump from advance auto worked great. You're right 2000XPSD there was no screen on the old carter pump and the bottom was plastic. The new pump seems to be much higher quality. There was a noticable improvement in power and top end, so the old pump must have been deteriorating for a while. I also had trouble with the old fuel line trying to kink while reinstalling the pump.

              RHSProstar, I didn't get the GPH or PSI from Advance, and it wasn't on the box. I also checked my fuel pressure regulator and it didn't have the PSI stamped on the top like some of the others I have seen. I did hold the boat on top end for a while and it never backed off, but mine only runs about 42 mph anyway. I think the E2044 pump is a good replacement, but the fuel line has real potential for problems and a good replacement needs to be found.
              Thanks for all the help guys..... Now if I can only get some help on my 1976 MasterCraft with the Escort Marine 255 Engine(Windsor 351)....

                Boofer, I don't know what year GM you're talking about but I have a 1998 Suburban 2500 with a 454 and it is on the 7th fuel pump. It's so bad the GM gave me a life time warranty on the fuel pump that is tranferable if I sell the car. I had 3 pumps by the time it had 38,000 miles on it. I am sure that is before the time frame you are looking at, but it tells you that GM has been having pump trouble for a while. I don't know if it is a carter pump or not, but I would bet that it is.....

                      Just read all the fuel pumpposts really helpful. My p/p burnt out last week and having seen all the details have now taken it out to find a replacement, The MC dealer in the UK quoted me approx $600 just to supply the pump !!! unbelievable.If anyone has a cross ref I can use in the UK let me know. Thanks

                        There was someone who sourced a aftermarket pump in Europe. I will have to do more of a search to find out more specific info.....

                            You guys are scaring me. I have a three week vacation coming up and i dont want to be stuck without a boat because of this problem. I have an 06 x-star with an mcx - have the pump problems been solved by the year my boat was manufactured? or should i get a spare pump just in case?

                              No. I think they switched to the new fuel pump sometime in mid-2007.

                              I think it's reasonable to suspect that fuel pump failures are more common in 1998-2006 MasterCrafts than in other brands of ski boats, but I wouldn't conclude that fuel pump failure in MasterCrafts in those years is imminent. By no means does this website represent even the majority of MC owners, and it's well-known that online discussion forums are more likely to display complaints than accolades. It's easy to get spooked by postings on the internet, assuming that something that gets posted a lot is a universal problem, but that just isn't true.

                              My buddy across the lake has a 2004 X-10. I don't think I've ever seen him run it with more than 1/4 tank, and I can't remember the number of times he's run out of gas (I've towed him in twice myself). Despite my dire warnings, his fuel pump is doing just fine.

                              I would be concerned if I ran the boat a lot with less than 1/4 tank, and I'd be concerned if I had ever run out of gas, but if neither of those things apply to you, I wouldn't worry about it.

                                Thanks for the above. When my gas gauge reads empty, I can look thru the side of the tank - it looks like there is still 1/4 tank remaining - so maybe i will be lucky.
