Indmar Fuel Pump Part Numbers

[NCSUmoomba]

Hey gang. It's been a while since I have been on here. Been super busy building a house and raising our new little boy. Barely used my boat in the past 3 or 4 years, took it out maybe 5 times since we found out the wife was pregnant... and that was the beginning of 2014. He's almost 4 now, and the house is finally done, so i'm itching to get back on the water. Got the boat out a few weeks ago to check things out and clean it up. Went to run it on the fake-a-lake, and that is when the trouble started.

Turned over a few times, but didn't catch. After a few minutes, I realized there was no fuel pump noise. So the fuse blowing had begun. Tried several things, but had no luck. I got both the pumps to run straight wired, but still wouldn't run. Sometimes it would catch and run for a few seconds and then die. Checked an blew out the fuel lines, didn't help. I realized that when checking the pumps, I had emptied the spin-on fuel filter. Filled that up, put it back on, and it ran for a little bit, then died. Checked all the little things, realized that the injectors weren't pumping much fuel. Long story longer, I figured one of the fuel pumps was dying. Boat has just under 600 hours, so it's time for some maintenance anyway, so I figured I would go ahead and replace both the fuel pumps, an then I won't have to think about them for another 600 hours.

First, so, like a lot of you, I have the Carter 152-875 low pressure pump, which is the Indmar 501006. Mine has 45940H18A stamped on it, which, as near as I can tell, crosses to the Carter P4594. This pump is about $60 online (Summit, Jegs, Rock Auto, etc.) as opposed to the $400 that places like Bakes sells it for. It looks like some folks use the P4389 as a replacement.

Second, the high-pressure pump is driving me crazy. Mine has 344 2490A stamped on it. Based on my research online the Indmar replacement for that pump is 495126. I saw a post where Larry confirmed that, so I trust that is correct. I can't really find it online easily. Bakes doesn't even have that part number. Skidim appears to have it, but its close to $350. I have also seen people state that it has been discontinued/replaced as well?

So does ANYONE have any thing that can verify or provide the correct part number? (Larry, you still around?) And if so, has anyone crossed it with another pump? I have found several pumps of that type, but are not sure of the OEM specs ( I have heard 28-33 psi, Indmar manual just says 30 psi minimum at keyup.) Also, several of the pumps I have found don't list their specs. Indmar doesn't "make" pumps, so there has to be a cross number for it.

Ones I have seen:
Carter P61171
Carter P61157
Airtex E8266
Sierra 18-7326 (and a bunch of other numbers)
Precision E16414 (Oreilly's)
Precision E16299
and several others.

I am losing my mind trying to figure this out. Please Help!

I suggest calling Ski Dim they were very helpful getting the right parts for my fuel pump on my 2000 Supra Launch DD. The were able to identify the right pump for mine.

I would also check to make sure that you have fuel getting to the pump. I have heard fuel lines getting clogged and starving the pump.

Good luck

I have this pump from my 2004if you want it. $40 shipped. Worked perfect when I took it off.

Skidim has it on their website, and it appears to be the correct part number, but they are asking $328 for it. If it is just one of the Carter pumps, which it looks just like it, then they are only around $100.

It's like I said, the Indmar 501006 low pressure pump is LITERALLY a Carter P4594 (or a P4389). It's not a other brand cross referenced part. I have seen prices online for this pump from around $200 to over $400 (skidim has it for $212). I can buy the EXACT same pump from Summit or Jegs for $56; Rock Auto has it for $51. There is no way indmar MADE the pump, it has to be some other OEM fuel pump manufacturer, and if they used Carter for the low pressure, then chances are good that it is a Carter as well. I am fairly confident that it is a P61171, but I can't figure it out for sure. Anyone else have any ideas?

[NCSUmoomba]

Thanks Stazi, but since I can get a brand new one for $55, I'll just do that.

Notice the numbers stamped on the pump 4594....

[td_in_nc]

I will be interested in seeing what you find out. Have you contacted Carter? If they say it is certified marine grade I would go with that.

[NCSUmoomba]

I haven't contacted Carter yet. I sent Larry a PM, so I was hoping he would chime it. One problem is that I can't find the specs for the Indmar 495126 pump so I can even compare it with anything. If I can get that information, then I could call Carter.

[trayson]

Did you ever figure this out?

[Hoopskier]

I ran through a similar problem with my high pressure pump needing replacement. Engine is an Indmar Assault 320 with TBI. Has low pressure pump, then a high pressure pump to the injectors. I used CARTER P61171 as a replacement for the high pressure.

[trayson]

had to get towed in tonight. Thank goodness for insurance, because a $500 tow bill would suck. That said, I'll be fuel pump shopping soon!

[NCSUmoomba]

Guys,

I never did figure this out last year, and then got too busy to even use the boat. So I am back on it now, but still having trouble finding the correct high-pressure pump. I got a part number from Larry, but it looks like it is obsolete. I sent him another PM asking for more help. I hope he has better luck.

The only one's I am seeing are the P61122, P61171, and the P5001.

Here are listings for the "correct" pump, but they are listed with a pigtail which I shouldn't need. Neither of these refer to the actual pump number:

So confused!

That said, I don't think that the problem was my fuel pump after all. because I replaced my pump and still had issues. I should sell my used one since it wasn't the problem!!!!

$100 and you can have my 2008 pump that I pulled that wasn't bad after all. :-D

[NCSUmoomba]

Thanks for the link trayson, but those Indmar numbers listed don't match mine. Yours is probably different since your boat is newer.

So I was out yesterday for the first run of the season. Boat died on the wife shortly after launching. I didn't think too much of it. We went to our play spot (20 minutes), chilled out, filled ballast, surfed a session. Then we were draining ballast and needed to move from where we were drifting. The boat died and wouldn't start again. it would crank, sputter up and die.

So I figured out that I wasn't hearing the fuel pump prime upon key turn. (this happened a week ago at home, but the next day it worked fine).

I started messing with wires and after trying a few places of moving around wires and sensors, I wiggled around the wires that were attaching to the bottom of the low pressure fuel pump. After that, I had the wife try the key and sure enough the pump buzzed to life priming up and we were able to start and drive no problem. It cut out once on the drive back, but we were able to get back just fine.

So tonight I'm going to take a look at those connections and see if making them bomber will remedy that aspect I've been having trouble with for so long...

[BrentC5Z]

Ever find any issues to fix?

We sat for 1.5 hrs waiting in line to leave the lake after a trouble free day & no start.

Pump buzzed as it should, once it did sputter to life but would not go above idle, then died after about 20 seconds. Think this is the heat soak issue with the single pump application.

Ordered the new $225 pump since it's the 2006 original. Marinepartssource.com

[Branden967]

I recently had this same issue. We ran around the lake for an hour or so and sat, had lunch and then nothing. It wouldn't crank over or catch. I was finally able to get it to turn over after it sat for about an hour and a half, i figured the problem to vapor lock and as I only have the single high pressure pump. Most guys on here add a second low pressure pump to feed the high but I went a conservative approach since that second pump runs about $400 bucks and Im bleeding money with this boat. I wrapped my fuel lines in tinfoil / Velcro together stuff thats supposed to keep out 90% of the heat. Ive run it a couple of times and haven't had an issue since. Im also way more diligent with running the blower and I also try and let it idle for 3-5 minutes before fully shutting her off for a longer period of time. If it dies on my again, Im going to add a second pump for piece of mind. Next time it does it, try and dump some cold water on the fuel rail and pump and see if that gets her running sooner.

[BrentC5Z]

Good plan. I may add some insulation wrap to mine as well.

[Branden967]

Heres a link to the stuff I used;

https://www.amazon.com/gp/product/B003HIV3BM/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

I mainly hit the metal fuel line in and around the block. Do forget the one between the fuel rails, I think that guys is the main culprit but Im not sure...

[NCSUmoomba]

Okay, so I'm finally getting around to replacing these pumps. Carter said the P61171 is the correct pump, so I ordered that one along with the P4594 low pressure pump.

Got the tank drained and went to pre-assemble the pumps to reinstall back in the boat. I realized I needed to swap over some fitting on both of the pumps. 3 of the 4 were no big deal, but the one the fuel/water separator threads onto is a problem. There is no way to get a wrench or anything on it, and I tore the treads up trying to get it off the old pump. I was going to double nut it, but I couldn't find any that size. So now I am in trouble. Anyone know how to get a replacement? The part I damaged is the part the fuel/water separator threads onto. Here are some pics. One of the photos isn't mine, just a reference.

WTF? Why can't I attach any pics?

Oh well, here they are:

You may want to bring it to steve ashworth performance in Fuquay - They were very helpful when I replaced my pump, had a lot of parts in stock. BTW are you still at State?

[trayson]

On my XLV, I don't have all of that. I go from the fuel tank, to an INLINE fuel filter via rubber hose. Then the rubber hose leaves the inline filter and goes to the LP pump. Then the rubber hose goes from the LP pump to the inlet of the HP pump, and IIRC, there's hard line from the HP pump's outlet to the fuel rail and beyond.

So maybe just get an inline filter and bypass the whole "fuel/water separator" that doesn't exist in newer boats.

[NCSUmoomba]

Don't know Steve, might have to check them out. Nope not at State anymore. Graduated in 2006, went back to grad school for a bit a few years ago, but didn't finish.

Got the part out finally, but did more damage. Added a photo to the album.

Grrrrr.... haven't used my boat in years (had a kid, and designed and built a house). Finally took some time to get it back on the water for what's left of the season, and this is what happens!

They are a high performance shop - When I replaced my fuel system, they helped me out with the connections - only place I could find in the Raleigh area.

Son is at State now, but they don't have a waterski/wakeboard club anymore - he was kind of bummed.

If you need a fix of getting out on the water let me know - always looking for an excuse to get out there.
