Re: Spare water pump. Reply #25 – April 08, 2021, 05:08:05 am Hi McNugget; Odd timing, but my original '99 Shurflo developed a leak during the Morro Bay trip. I got the 4008 replacement. Took a week to get here in San Diego, from Oceanside, by way of Indiana. It's not installed yet. Sealed the wood floor, a drip tray is in, and I'm modifying some wiring to put a switch/light in the bathroom. Easy to do in the TK. Not going the three way switch method, just another switch in parallel. The old pump just developed a leak in a seal at the bottom. My old pump was a three chamber, and marked for 2.75 gpm. The new pump is a four chamber pump, marked for 3.0 gpm. Amazon.com: SHURflo 12v 3.0 GPM Revolution RV Water Pump # 4008-101-A65:...

Re: Spare water pump. Reply #26 – April 08, 2021, 10:39:36 am An 'issue' with repairing or replacing the water pump in an older TK is that access to the pump is only through the small opening when the bottom drawer in the sink set-up is removed. Newer TKs may have easier/more convenient access, but trying to even see into the tiny space, let alone get ones hands in there to work on or replace a pump in an older TK is not easy. I ended up having a shop replace the original water pump; young, limber tech with non-ham hands. 3 Likes
Re: Spare water pump. Reply #27 – April 08, 2021, 01:04:43 pm Hi Joan; Yes slow, tight access. When I first got 'Bluebelle', I didn't like the way the drawers didn't pull out all the way, so I changed all three to accuride full extension drawer slides. I had to cut away face frame on each side of the drawers to put the side rails in. The 'closed' retainers didn't work, so I put magnet catches to hold them shut at the backs. They work Really well! Even today 19 years later I find myself trying to lift them, even though I just have to pull hard. I've been able to access behind and under easily. If something pops up to prevent a drawer from opening, I can pull out all three clear at once, and I can retrieve things that fall out the backs onto the pump. Working on the pump, I pulled out all 3 drawers just by flipping a little lever on each slide. The side rails are still in the way, but not like the original center slides would have been. I took out the LPG detector temporarily to expose more from the side. 3832E|Classic Full-Extension Slide|Accuride International Newer models of LD TK's reversed the drawers and cabinets, so that the drawers pull out from the driver side. So I assume the pump stayed in the same location, and with the floor inside the cabinet removed; it should be easier to access the pump. I'll try to come up with some pictures. RonB 1 Likes

Re: Spare water pump. Reply #29 – September 26, 2022, 04:49:21 pm Resurrecting this older thread mostly because the pics from #10 and #20 had me thinking about adding the upright housing to my 2001 MB. My pump died and I’ve already got the replacement working, but that upright housing looks pretty sweet for future replacement work. Any reason why I should not attempt this (as long as there’s no strain on the in/out pipes)?Thanks in advance.Chris
Re: Spare water pump. Reply #30 – September 26, 2022, 08:24:43 pm Hi Chris; (not Horst). I would mount the pump with the motor up. That way leaks won't get into the motor, and the inlet to the pump will be more on the level of the bottom of the tank. With low amounts of water, should you lose prime, it might take awhile to get water back into the pump with the inlet 10" higher. I would put a drip tray underneath, and a powered electric water detector in the tray. In my case with a 'TK, 12v is available right at the LP gas detector with it right there.

Re: Spare water pump. Reply #31 – September 27, 2022, 06:40:34 am Although this post is a couple of years old, I now have a little more experience concerning carrying a spare water pump that could potentially help another newbie like myself!I had read about the problems with the model in my '09 (shurflo extreme 5.7) so I carried a Revolution 4008-101-A65 just in case. Sure enough on our first big trip last year the Extreme did act up, though not enough for me to replace it at the time. Good thing I didn't try to replace it on the road since the Extreme's intake connection isn't compatible with the Revolution's. When I went to swap them out this summer I realized this. It was also a major P.I.T.A to get the correct connection. Make sure you have all the needed parts along with the Evolution 4008 replacement if replacing another model pump!I needed the Shurflo Swivel Elbow part# 244-3926 for the intake side of the Revolution 4008 pump.
