Happy to lend a hand when ever needed. Next up is finding my ground problem that I believe led to this corrosion of the fuel pumps. I hate electrical stuff. I am a mechanical engineer, not a EE.... -
Thanks for the words of encouragement. These new Millennium fuel pumps are a lot easier to rebuild than the Carter fuel pump. I would like to find replacement fuel pump cartridges for the Bosch versions. Bosch and Millennium have been completely silent on this topic when I've emailed them for info....Leave a comment:

I was able to find the two exterior filter socks and the internal strainer filter. I cleaned the rust from inside the plastic hosing and wire wheeled and sanded the fuel pump cartridge housing. It’s back together and works. This will be used as my backup fuel pump now. The picture of the box is the...

Anyone replace their stock aluminum exhaust manifolds on the L18 (8.1L) engine with cast iron manifolds and elbows? Inboard Online sells the complete cast iron set for about the same price as the replacement aluminum manifolds. To install the cast iron version, there needs to be some "trimming...Leave a comment:

I rebuilt the original Carter fuel pump because it was not working. I replaced the cartridge and reinstalled it in the boat. However, the boat still would not turn over. So I replaced the entire fuel pump assembly with a new Millennium pump. Only to find out the fuel pump relay was bad. So now I have...Leave a comment:

Aside from the fuel pump relay and MAP sensor going out, the engine has always run. However, it hasn't run 100% for the past 1.5 years. I now know why it would only run to 30 mph. I do have a tendency to run the fuel tank down below a 1/4 of a tank but even then, it would still run. It has 1/2 a tank...Last edited by prostar205; 01-11-2022, 06:03 PM.Leave a comment:

Correct - the green ground wire that is attached to the spade connector on top of the fuel regulator does not provide a ground path to either of the fuel cartridge pumps. The regulator is isolated from the metal top of the fuel pump assembly be a rubber grommet. The two fuel pump cartridges are grounded...Leave a comment:

I plan on installing the original fuel pump assembly. That one only has a single fuel cartridge and it worked for 20 years and 700+ hours. I want to find out why this happened so it doesn’t happen again before I buy a new $800 pump.Last edited by prostar205; 01-11-2022, 10:55 AM.Leave a comment:

I forgot to mention - both of the Bosch pump cartridges work without any issues. I just bench tested them and my boat ran "OK" when I winterized it. My big issue is I don't want to buy another new pump ($800) and have this happen again. I need to figure out what caused this....Leave a comment:

The dealer I bought the pump from said no problems grounding the new pump with the green wire. They said they have replaced many of the Carter pumps with the new Millennium pumps and they hook the green wire to the top of the fuel pumps regulator, just like I did....Leave a comment:

Tried looking them up and found a number. Called and left a message. Hope to hear back soon but not counting on it....Leave a comment:

There is a place on the pressure regulator for a ground wire. The only ground wire in the original harness is the green wire that is part of a 3 wire loom that connected into the yellow connector on top of the original Carter fuel pump. See picture below.
The new Millennium fuel pumps do...Last edited by prostar205; 01-10-2022, 02:00 PM.Leave a comment:

I took a sample of the gas that is currently in my tank. Went all the way to the bottom of the tank to get a good sample. Let it sit for 10 minutes - absolutely no water. That doesn't mean there wasn't water in the tank 6, 9, 12 or 18 months ago. It just means there is no water now. There is about 30...Leave a comment:

Only use super unleaded, non ethanol marina gas. Yes, I use Staybil once a year while I am winterizing the boat. This fuel pump has only been in the boat for 18 months. I just can't believe that much rust can build up in 18 months....Leave a comment:

Anyone rebuild a new Millenium Fuel Pump??
Curious if anyone has rebuilt one of the new Millenium fuel pumps? I finally replaced my 20 year old Carter fuel pump back in Aug. 2020 after ~750 hours of operation. Well, after 1.5 years and about 65 hours of operation, my new Millenium ($800) fuel pump is trashed. The pumps still work fine. The biggest...

Yes, I attempted to rebuild the original fuel pump back in Aug 2020 when I started having problems. Decided against that and bought a brand new Millelium pump (PN 155215). That is the PN that MasterCraft says replaced my original 20 year old fuel pump. What you see in the pictures have only been in...Leave a comment:

I have only used marine Staybil on a yearly basis during wintering. Recently I put in fuel injector cleaner and Seafoam in the fuel. Wondering if the combination of the Staybil, fuel injector cleaner and Seaform could cause the corrosion? The fuel injector cleaner and Seafoam was put in about 5 months...Last edited by prostar205; 01-10-2022, 10:54 AM.Leave a comment:
