Fuel pump aftermarket part numbers

[rhsprostar]

The 2044 will work fine for your application.

When you replace just the pump and not the whole module you don't have to worry about boat specific part numbers.. The difference is that each boat has a different shape gas tank and when you replace the whole module you have to make sure that you get the proper size module for your specific tank. When you are just replacing the pump you reuse all of the module components and therefore do not need to worry about the specific module numbers.
In other words an mcx is an mcx is an mcx, no matter what boat it is in. The actual fuel pump is the same across the board.

Hope that makes sense.

Can someone pm me the pdf chart referenced above or send a good link. I would love to see what mine is in the reference sheet and can't open the link.
Thanks,
Bill

Can someone tell me what size tool I need for the fuel line couplers? I was looking at Napa and they have one tool that works on 3/8", 1/2", 5/8" & 3/4" Fuel & AC Lines. Wondering if any of these sizes match

I do not remember the size of the fuel line tool but I believe thay are color coded. It is the blue one.

After reading all this I'm still a bit confused what part number do I need to order for a 06 x2 with a mcx canadian napa number or equalivant. Would love to buy a spare thanks

Napa e2065 (canadian part) will work and fit perfectly. There are a few cheaper alternatives but this one is confirmed so is it worth it to save $25?

A word of caution though. If you are still running the original pump, it's not IF your pump will fail it's WHEN. They will all fail eventually with the factory setup from those years....

You may want to swap it out for peace of mind. It could easily ruin an outing, weekend or even vacation.........

a bump for a great thread. i have a 06 x-45 the quit running last weakend. the fuel pump went out. i almost bough the pump from mastercraft but i found this thread frist. i intsall the Airtex E2044 just now and the boat fired up and is running great. im not sure if this pump is going to be enough for the 8.1 so im going to put the boat threw its paces this weekend. the pump cost me $79. thank you all

I asked (I believe more than once) about whether or not the pump is the same for the 8.1. I never got an answer. I finally just gambled and got one that crossreferenced with the Airtex 2044 (it was a Bosch, as I think they have a repuation for a bit higher quality...at least according to one friend). It worked great until I sold the boat 8 months later.

As I understand it, the same defect still exists, even when you replace the pump. You will still have a fuel pump that is sitting high and dry whenever you run the tank low and it will overheat and die a premature death. Changing the pump just gives a new pump a chance to suffer the same death. Is there a reason to believe and new pump is more resistant to this?

The design of the in-tank pump is indeed the root cause of the the frequent failures of MasterCraft fuel pumps, but I think the problem was exacerbated by the poor quality of the Carter pumps they were putting at the heart of the device from about 2001 to 2005. My understanding is that they switched suppliers for 2006.

The problem is that the pumps are running dry because of lack of fuel to pump when the fuel gets below a certain level, or that fuel tank debris is clogging the fuel filter when it has to filter below about 1/4 tank, and that limits fuel flow. The pump needs fuel to lubricate and cool or the impeller fries. In either case, the ability of the pump itself to tolerate running dry is likely to be a contributing factor as to whether or not it fails and how often.

We won't know for awhile, I guess, until we see a statistically significant number of failures of all these user-installed Delco/Airtex/NAPA pumps and we can see how the bell-shaped curve is shaping up. That took several years for the original pump. If these aftermarket pumps are better, it may be several more years before we can draw any meaningful conclusions as to longevity. Maybe they will even hold up for a period of time that begins to represent a reasonable failure interval. Maybe the Carter pump was the whole problem.

As far as I know, MasterCraft hasn't changed the design of the in-tank fuel pump system, but maybe they've change the parts suppliers. Again, we won't know for a few years, but even with so many people tuned in to fuel pump problems, I sense that we're seeing fewer failures in the 2006-and-later MasterCraft OEM fuel pumps.

The thing I'm curious about is whether or not using an aftermarket higher-quality fuel pump will allow users to forego MasterCraft's absolutely absurd "fix" for their problem -- recommending never letting the fuel level get below 1/4 tank. What a ridiculous solution.

Swapped mine out today with the Airtex. Flex hose was clear (urethane colored). Was able to reuse it, so that was a bonus. Easy swap. Removing and reinstalling the 12 socket head screws took the most time.

And I was seconds away from the pay now click when I thought to myself *** 500.00 for a fuel pump just doesn't seam right...
Gonna pick up a 2044 Airtex for 80.00 buck and try my luck.
The info on this website is a true blessing. I'd love to buy you all a beer or the drink of your choice...**** I could buy you guys a couple of rounds for the money you saved me.
THANKS
Oh I read every page. and every page on every other fuel pump related thead on here. A little concerned as always prioir to doing something new, but looks pretty straight foward after reading all of this.

[deminimis]

The 2044 fed the 350 MCX all weekend without a hiccup.

[krutzmart]

Sweet

was the swap out a painless as it look in the forum ?

[deminimis]

Yes, but I got lucky as I was able to reuse the flex hose. If you have the same hose (and after you carefully remove the single-use hose clamp), you might use a hair drier to soften the hose slightly to allow it to come off the barb easier. If you have the other type of hose that doesn't do well with this swap, invest in the proper in-tank hose. My X-tool did not work on the fuel line disconnect, so ended up using the blue one here:

[krutzmart]

Your talking about dis connecting the in-tank hose. It sounds like it can be cut off and reused. I was planning on replacing but havn't tested pump to be sure thats my problem but, gonna replace it anyway as everyone seams to have problems with the carter pump.

[deminimis]

Fuel feed hose needs the blue tool (or similar -The orange "foreskin" covered hose that you see laying right on top of the tank). The in-tank hose in my above pic might need the hair drier. Sorry about the confusion.

[krutzmart]

Got it. Thanks for the tip.

I'm not too much of a man to stop and ask for directions when I'm Lost.

Gonna get that tool and my new pump from autozone 2044 Airtex, 1 ft of the SAE 30R10 submersible line (just in case ) 5/16, I'll try to reuse in tank line, got the heat gun and hair dryer ( the wifes ) to soften the in tank hose.
AND GO TO TOWN....
