What is everyone recommending for a replacement fresh water pump?
Bought and installed this in 2014. Love the variable speed. Still going strong (higher price today lol). I purposely went with lower flow (lower GPM) model because I boondock a lot.

I also suggest using flexible hoses to connect the pump. You can overpay for a kit like this, or just go to the hardware store and buy sink connector hoses with proper fittings on the end: Shurflo 94-591-01 RV Water Pump Silencing Kit (https://www.rvupgradestore.com/RV-Water-Pump-Silencing-Kit-p/86-8349.htm)
I installed the Shurflo 4008 back in 2016 and have had zero problems with it. It's quiet and does the job. Installation report below:

EDIT: Looking back at my old post, I realize that I later modified the pump installation I described above. After using the Shurflo 4008 for a while without the pressure accumulator tank, I decided to reinstall it. If curious, you can read Reply #12 and Reply #15 in the thread linked below:

Lower GPM is also a much lower current pump. Our '03 had the -ARV 5.3 GPM version, and there are caveats in the AquaJet manual about wire gauge and the Intellitec relay module used for the higher GPM pumps:

1.
Determine whether or not your RV is currently using an 'Intellitec' pump controller (i.e. three or more "momentary" type
switches which can be used to turn the pump on/off.). There are at least four (4) different types of Intellitec controllers
currently in use, but not all of them can be used with the Aquajet RV. Specifically, only a four terminal, 10 or 15 Amp rated
Intellitec controller can be used to directly control the Aquajet RV. Intellitec 7 Amp, 3 Amp or non-rated controllers should
NEVER be used to switch the load of the Aquajet RV.I mention this in case someone with an older coach wants to install the higher flow rate pump. Due diligence would be wise in checking your existing wiring and relay. Our '03 was fine, but if kgrover is looking to replace the one in the 1991, not the 2004, the lower GPM would be a better option.
Shurflow 4048
Same. Shurflo 4048. Works well
My coach had the Shur Flo 4008 which was a replacement for the OEM pump and has the small expansion tank. I recently replaced it with the AquaJet ARV only because I got it for half price at Rural King. I would say they both work fine and I didn't need to replace the pump but now I keep the old 4008 as a spare and also as a transfer pump if I ever wanted to add fresh water to the tank where a pressurized water source isn't available. I would also add that I think you're not supposed to use the Aquajet with the expansion tank. I left mine installed and the pump operation is a little erratic so I will remove it.
If you go with a Remco pump, be careful which one you get. I installed the Remco Industries 55AQUAJET-ARV pump a couple years ago, and the pump was noisy and short cycled from the day I installed it. About a year ago, I finally called Remco and was told that the pump was designed for high flow applications and there is no way to keep it from short cycling in lower flow applications. I ended up giving the pump away and replacing it with a generic pump from Amazon. It has been going strong for a year and I couldn't be happier.
You do not need to remove the expansion tank. In fact, it's much better to keep it installed to allow for expansion when the water heater gets hot. INSTEAD, precharge the expansion tank to a PSI that is above shut-off pressure of the variable speed pump. I can't remember what number I used, but I think I have it in a way old post.....but my guess is 75-80PSI might be a good starting point.
And the benefit is that at 80psi, the expansion tank can the increase in volume that occurs when water heater goes from cold to hot.
