Submersible Water, Fuel and Diesel Transfer Pump 12V | Portable and small - Produces 2.69 GPM |Ideal solution for Barrel, Tank, Camper, Trailer, RV, Boat

Seems to work fine, powered with  12V 6A AC/DC Power Adapter with 3-Prong Plug, UL listed for 3528 5050 RGB SMD LED Strips , driven by MOSFET RFP30N06LE from Gikfun RFP30N06LE TO-220 Mosfet Power Control DIY Kit (Pack of 5pcs) For Arduino EK5001_Dx5  (flyback diodes built in) with heatsink 10 Pcs Complete TO-220 Heatsink Kit, by Tech Express  and a water detector cobbled together from a few transistors. Have not done long duration testing yet, just a bunch of on-off cycles for minutes at a time to check nothing overheats. May turn out to be 5 star.

I'm using this pump to transfer diesel fuel from one tank to another. It seems to be well-made and sturdy, and in testing it has performed well so far. In fact, I'm impressed with it enough that I'm considering getting a second one to use as a pump to get that last little bit of water out of the bilge. I can't comment on its longevity since I've only owned it a short time and haven't used it much yet, but I'm expecting it to do well.

Great little pump, using it for a mini sump pump for ground water. No problems, has been working for over 1500 pump cycles.

I wanted a pump for a portable shower when camping. I will heat my water to about 110-degrees Fahrenheit and put in 5-gallon bucket, then drop pump connected to 3/8" silicone tubing on one end and cheap RV shower head on the other. What I like about this pump is the length of the power leads as well as the fact it will fit through a 1-1/2" bulkhead fitting with just a nudge of "persuasion". Going from memory, draws about 35W (3A).
