      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.

              Boofer, Thanks for the quick reply. Do you know if anyone has any photos posted of the EP356 or equivalent. I looked on a couple of Auto Parts web sites and couldn't get a good enough picture to tell if the same as mine. Thanks.

                The ep356 should be fine for the mcx. You should just check that the fuel pressure is at 58 psi after the install and off you go. If you want to really be careful you can always check the pressure stays constant at different rpms and/or boat speeds.
                My boat had the 323 pump for an LQ9 but it was of the returnless line variety. I think(not sure) that all of the MC systems use the same actual pump but the modules differ for each different tank configuration for each boat model.
                Have you got a picture of your module?

                  i crossed the ep356 to a napa p74122. i don't know if it works yet as i just picked it up as a spare to have on the boat. I ran the tank pretty low a few weeks ago and just bought the new pump to be safe. Here's a poor pic:

                    What are the pump specs? GPH? psi? That will give you an idea if you are in the ball park.

                      rhsprostar and 2000xpsd, Thanks for the help.. I took pictures after I took the module apart maybe it will help to have the pump pictures matched up to the 2003 Xstar with 350 MCX, My pump connection look a little different from the pump in the bag. It looks like the return from the regulator on the plate has a place in the bottom to dump the fuel back to the tank in addition to the return line from the injector manifold. This is first time uploading pictures so bear with me. If any one recognizes my pump as an exact match to anything they have bought in a parts store please let me know..... Thanks again for the great help.....

                        looks the same to me except for the maybe inlet where the strainer would go. someone will have to verify that as i haven't taken the mc one out yet
                        sorry for the poor pix...stupid treo

                          I replaced my fuel pump a few weeks ago with the AC Delco EP356. Thanks to everyone on this forum I was able to install and put everything back together correctly (took me less than an hour). So far so good. My boat has started on a dime everytime. I bought mine from www.rockauto.com for $110 including shipping. I figured I saved myself over $500 doing it myself and not buiyng the enitre MC fuel pump module.
                          To some golfers, the greatest handicap is the ability to add correctly.

                            I just got back from Advance auto parts with a Master E2044 electric fuel pump. The 1st photo -bottom end with the Advance part no. visible, 2nd photo - top with connetions, 3rd photo - side by side of my old pump and new pump from top, connetions are almost identical, 4th photo - side by side of bottom, new pump has a screen and machined aluminum intake area, old pump appears to be plastic. The new pump appears to be much better quality, it does appear to be slightly different than 2000XPSD's pump. The new pump cost $82.37 including South Carolina 7% sales tax. (And so you don't have to look around for an earlier post to identify what this pump is for) My boat is 2003 X-star with 350 MCX, the fuel pump module MasterCraft part no. is 155193 (This can be found in one of Boofer's earlier post), the actual pump has 323 and 3D01A (or 3091A, can't tell which) Carter written on the side of it. By the way when my boat quit, I could still here the pump motor running for 3 or 4 secs after turning the key on which was somewhat misleading. After getting the pump out I tested it and the motor seems to run fine but the pump will not even blow bubbles much less liquid from the output side, so if you can hear your motor running that doesn't mean is is working. Hope this helps... By the way, who do I need to send the check to for helping save the $300 from MasterCraft LOL....

                              what was on the bottom of the original pump for a strainer? From the looks of that one it looks like nothing to me. I like the screen in the other one.
                              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.
