Recommended Replacement For A Shurflo 4008-101-F65 RV Water Pump

Question

Question:

I posted a comment and then realized that would not be yall answering. So re: Q/A Replacement Water Pump for Shur Flo 4008-101-F65 in Winnebago Vista 31KEinch Id like to know: Please look at the answer put there. My question is wanting to know if the Seaflo Diaphragm pump being suggested as a replacement for the SF F65 NOT E65 has the same wiring that the F65 has. The F65 is a SF 4008 made for Winnebago and has a different wiring set up. To use, for example, the more common E65 same pump, just different wiring it would require a modification on the wiring. I dont think simply having get same flow rate etc makes it a replacement. But perhaps Im wrong. Please let me know. Mine just quit working last night. Thanks.

Hi Dorothy,

The Seaflo Diaphragm Pump # SE58FR would be a compatible replacement for your Shurflo 4008-101-F65, but it has a lower psi rating so you'd see a bit of a drop in pressure. Instead I recommend going with the Seaflo # SE57FR. This unit has a 3.0GPM, 55 psi rating, and operates on 12v DC power. Everything I can find on the 4008-101-F65 shows it being 12v DC but we can clear up any confusion by checking where it gets power from. If it runs to the battery or to a fused port on the DC distribution panel then we know it's 12v. If it runs to a circuit breaker in your AC distribution panel then we know it's 120v and you'll need a different pump. Both of your distribution panels should be labeled so you can quickly find the water pump.

If yours just suddenly stopped working then I would also check the fuse/circuit breaker to see if maybe it just popped and needs to be reset/replaced (fuse) and could continue to work. If not then the motor could have failed and complete replacement would be needed.

THX Kevin. First, I submitted 2 of the same questions thinking I had done it wrong the first time so I also got a reply from Jameson C. Sorry to waste resources there! This is how I replied to JC’s response: “ Sorry. I’m not mechanically inclined and in my former Winnebago RV i was able to change out my ‘apples to apples’ ShurFlo E65 w/ a new E65 myself. All the same. No problem. My current WB RV has a ShurFlo F65. It is twice the price of the E65 so I researched. I found: The Shurflo 4008-101-F65 is an OEM unit with electrical connectors that are specific to Winnebago/Itasca RVs. Someone in a chat room also said: “The F65 has the connector Winnebago uses. If you purchase the E65, you will have to cut the connector off and wire nut or butt connect the wires together.” So I was looking for a more affordable replacement for my F65 with the Winnebago wiring intact and thought you [Jameson] were saying the Seaflo is a total replacement when I found a similar question you had answered. I realize the PUMPS are the same but wouldn’t know myself how to modify wiring so that’s why I was asking about the wiring on the one you said is a replacement for F65. My buying the F65 will still be cheaper than having to take it to an RV repair place so I’ll likely do that. Thanks. “ HOWEVER now to Kevin! Since my actual pump was running and just no water flow I did a couple of troubleshooting tips (removed the little round filter & rinsed, tho it was clean anyway & tapped the diaphragm area with the handle end of a screwdriver) and it’s working great again! So thanks to both of you AND PLEASE CONSIDER THE FOLLOWING feedback FOR THE FUTURE: we are not all mechanically able to DIY in many cases. If you go back to my original question it really was the WIRING only I wanted to determine if it was going to be the same as the WB OEM ShurFlo F65 (as Jameson said in the original similar question response that the Seaflo i was asking about IS a replacement for the F65 so I feel that to be misleading and assumes anyone asking might assume apples to apples and/or whoever is asking is capable of then learning upon buying that wiring modifications would be necessary and could do them.) In this case the difference in wiring should be mentioned when saying another pump is a replacement. Yours was a more detailed answer to me than his, which I appreciated your detail of saying the pumps were not the same either (even tho it would work w/a wiring mod) and gave me a better option for same pressure etc. I know I’m being very wordy, yet as a person (and an elder) who can do things like change Gen oil w/a youtube vid or a water pump IF TOTAL apples to apples) yet sites like this seem to assume if ur thinking of buying a part you must be a decent DIY’er and things like this -where a wiring mod IS needed isn’t thought of to be mentioned. Thanks if you hung in here and read it all. And thanks for your response. Take care.

@DorothyT I'm glad the troubleshooting tips you followed to release the diaphragm worked. If this was the first time using it after being winterized then I'd say this is probably a one-off occurrence. That being said, the diaphragm is typically the first part to wear out on a pump. Another indicator that the pump is failing is if you get water in your fresh water holding tank when hooked up to city water. 99.99% of water pumps are going to come with just bare wires (no connectors) but crimping on some butt connectors only takes a few seconds. That being said, you can also take it somewhere to get installed and it shouldn't take more than half hour to complete the job. Manufacturers love to use proprietary components so that you're forced to only buy through them. Most people will avoid the manufacturer mark up and just cut the connectors off and use a butt connector or wire nut. I'm glad it's all working out now though, if you need anything else just let me know.
