My only concern for having an external pump is damaging it. I don't want to have to think about what I put in the frunk. I still want to off road and take corners fast. I don't want to worry about something being damaged or not be able to use the frunk the way I intend to. Not opposed to it, i'll just need to figure out a way to protect it. Just to be clear, the tank is going to be shipping with the submersible pump as standard. The surface mounted on demand pump will be an optional item for any user that wants to run longer hoses or who wants a bit more pressure for the sprayer. That being said, it may not come through in the video but the 42 series pump is fairly tanky. Unless you are putting something quite heavy in the frunk and then leaving it untethered to slide back and forth violently while you're off-roading--something you obviously shouldn't whether the pump is there or not--then I don't think it is an issue.

So… shipping with submersible pump means we are back to being able to keep lower frunk shelf flat in place except when tank is in active use (to allow hose/wiring when in use)… is that correct? Thanks. Oh… and did you provide DB noise estimate using the submersible?

Thanks for the update! I personally gravitate more toward the larger Seaflo 42 pump, both for its power and quieter operation. Since I intend to compliment the water tank with the cooler/freezer you are designing, the frunk isn't where I plan on storing gear for camping or a day at the beach anyway. If it is easily removable as you mentioned was part of the design, then that takes care of everyday use of the frunk when I don't need the water tank. With the gear tunnel shuttle and manual tonneau cover (coming s00n), there will be tons of storage space otherwise. Quick update on retrofitting a 12V outlet in the frunk, I can't for the life of me find the correct metri-pack terminals to fit the connector used in the truck (at least in the US). So I just went ahead and bought the same connector that comes with the correct terminals from AliExpress (credit to @rhuber over at rivianforums.com for finding the connector). Shipping will take a few weeks coming from China, so I will post another update once it arrives. I will be following your progress with great interest.

Not really loud enough to bother even sitting in a bucket, (as in not inside a sealed tank where it would be even less noisy).

Apologies if I missed an earlier update (haven't been following the thread closely since placing my deposit), but have plans changed wrt the pump's power source? I'm one of those who has no 12V port in the frunk (and likely won't be interested in splicing one in), so I'm very curious what the design supports now.

I'm one of those who has no 12V port in the frunk (and likely won't be interested in splicing one in), so I'm very curious what the design supports now. There was a supply issue sourcing the 38mm pump and we had to switch to a 50mm model. The new pump is slightly higher wattage, (72w vs 48w) so the rechargeable battery will need to be 12VDC 6A. I have already ordered sample battery packs to double check they work correctly. So short answer, we did have to change pump models which requires a slightly different battery configuration for those without the frunk plug, but everything will essentially still work the same--so nothing to worry about. I will be sending out an email in the next few days to all reservation holders to update everyone on our progress.

When do we need to decide about if we want to add the battery to our order?

When do we need to decide about if we want to add the battery to our order? I will be emailing everyone on the reservation list in the next few days with some specifics. I want to test two sizes of batteries--3,000 and 6,000 mAh to be sure everything works as expected before we make any decisions. As of now my thinking is that for most people it will boil down to size and time between recharging preference more than cost as the differences is small--something like $5 - $10. I don't have the dimension here in front of me, but the 3000 mAh would be roughly the same size as the battery I have linked to on Amazon previously, (about cell phone sized but 1" thick) and the 6.000 is the same but 2" thick. It would certainly be better cost wise if I can ship them with the pumps, hoses, and all the machined parts. So short answer, I don't know exactly when yet, but soon--the next few weeks.

Sorry this is a long post, but you guys seem to like being kept up to date and my sharing lots of details about what is going on. I found some video of the little Seaflo on demand 4 amp diaphragm pump that I mentioned we are going to be testing in the hopes that it is quieter than the other models we have tested so far. The company rep I spoke with told me it was about 65 db which is about the same as a spoken conversation. After seeing the video I am a lot less hopeful that the 65 db claim is accurate. I am including a link below so you can have a listen for yourselves. 4 amp diaphragm pump video.The pump SEEMS much quieter at the start of the video and gets much louder when the phone is placed fairly close so it is still possible it might be OK, but it sounds very similar to the units we have already tested so I am doubtful, but we shall see when we get our test sample. If it turns out to be too loud--which as I mentioned is my expectation now--I just don't think there is any model of the "micro" diaphragm pumps in the 1.5 to 4 amp range that will be as quiet as most people would want for our application. In the "small" size category, (so one size step up) there is a very quiet Seaflo 3 GPM (gallon per minute) 55 PSI pump that pulls about 7 amps at startup and then about 3.5 amps continuous. The trucks 12v can run that no problem, and it can also be turned down to say 45 PSI which would lower the max draw at startup to around 6 amps for those concerned about battery drain. It runs much more quietly and is what I personally would want to run where sound levels are concerned. I will include a link from Amazon that has a video you can listen to below. Seaflo 42 Series.The downside is that it is a fair bit larger--about 1.5" taller and 1.5" longer--and almost 3 x more expensive. The price difference mostly comes down to it being higher performance--more flow--and very quiet. Obviously it's more flow and PSI than most users will need or want to pay for, so I think if the last little 4 amp pump we're going to be testing doesn't work out, (again that is my expectation at this point) we're going to ship with the 52 mm 6 amp submersible pump. For anyone who does want to run longer hoses or needs the increased PSI, I am going to design a hatch plate with a built in mount for the Seaflo 42 series and offer it as an "easy swap" option. Basically 6 screws and about 10 minutes to make the swap. Depending on how much interest there is, and what you guys want, I can offer it as just the hatch plate mount and you buy your own pump off Amazon, or turnkey with the power plug and fittings already on, fully assembled. Just a quick update for the smaller on demand Seaflo pump from the first video link above. After testing it turns out that it actually is quieter than any of the other micro OD pumps we tested, and that the video does make it seem a little louder than it is in person. That being said, it is likely still a little bit too loud for some people, especially those that don't need the higher pressure spray. Overall I am impressed with the pumps pressure output and it's amp draw at 2.6A in our testing. The build quality seems very good on it as well. I think it could be a viable alternative pump for those wanting a higher pressure On Demand type pump that are OK with a little bit of noise. I think it is certainly worth testing installed and in place in a frunk to see how it sounds there. I will post some videos once we get to that point.

Thanks for the updates! Honestly couldn't tell you what PSI/flow we'd need personally, but we are on your list for the kitchen so would be interested if you have a way to test the smaller pump with that long of a run and acceptable PSI for washing dishes.

Honestly couldn't tell you what PSI/flow we'd need personally, but we are on your list for the kitchen so would be interested if you have a way to test the smaller pump with that long of a run and acceptable PSI for washing dishes. Having the Camp Kitchen take advantage of the 12 gal frunk take is a high priority for me as well so I intend to test both the micro Seaflo OD and the larger but quieter 7 amp Seaflo OD pumps for use with the kitchen. If I had to speculate at this stage, my bet would be the larger OD, (On Demand) pump for the kitchen, and for those that just want a boost in pressure for using the sprayer, the smaller OD pump. I think most people--maybe 80%--will be fine with the 50mm submersible the tank will ship with as "standard", and those of us with a special use case can easily switch to the best pump for our needs--it's basically six small screws and about 10 minutes to swap them. The most important part will be having a solid tank that fits well and is easy to fill, and we have that in spades =)

Marsha should be sending out a progress report email today for those not following along here in the forum thread. Of course anyone not following the thread won't see this post anyway =)
Kidding aside, please let me know if you're a reservation holder and didn't get the email.
