Works as advertised and provides for longer uninterrupted power. Has anyone found a way to plug one of the hoses when only using one generator?

This system works well and does what they say it will. I bought mine in April of 2019 so I don't know if it has changed. One of the things that could be improved is the shape of the tank. If you want to rotate the gas you can turn the tank upside down and remove the cap but in that position the cap is in an area that is raised so the gas won't drain completely. Loosing the cap to allow air in is a little hokey in my opinion. It would be better if there was a valve on the cap to let air in.

Running this with two Honda 2200's. Works great with both generators and if you want to run just one, you can, no leaks. I haven't tested run time with two generators, but I ran a single 2200 for roughly 36 hours and did not have to fill the tank at all. I drug my feet way too long before buying this, so worth it.

First off I have not ran fuel through the tank or lines yet so I cannot say I have tested the system. However it's a Attawood fuel tank, some fuel lines and misc brass and quick connect so there is not much complexity and I'm confident it will do just fine. You will notice in pictures I added my own quick connects to the "T" are where the lines meet the tank. They are way overkill as they are rated to withstand thousands of PSI and very hot fluid but I have access to them at my job so I put a pair on. They have Viton seals so they will be resistant to fuel. If your planning on doing something similar. My QC's are 1/4" brass closed (not open flow) with Viton seals and I used a 1/4" hex nipple.

To summarize: Build quality appear good but haven't used yet. DOES NOT come with QC's where the lines meet the tank. I added those. You have a lovely day now.

I hooked this up to 2 honda EU2200i generators in parallel. Filled it with 5 gallons of gas (yes, it holds 6) & ran the two generators for 30 hours each over the weekend. When we packed up camp there was a trickle of gas left in this tank and the integrated tanks on the generators were still almost full.

We were able to keep the A/C on for two days in the 100+ degree heat of southern AZ. I left the Hondas in eco mode all weekend & never worried about the fuel. We ran only one generator from sundown to sunup each night and both of them sunrise to sunset each day (thus the 30 hours each).

The setup was easy, with good instructions and more than enough teflon tape provided. Yes, it is VERY easy to cross-thread the aluminum caps onto the plastic threads of the generator. Use care. Also, be careful when removing the tether for the OEM gas cap on the generator. There is a spring loaded pressure valve in the OEM cap. The retaining washer and spring will fly away when you pull the pin. Using a needlenose carefully pull the cotter pin out so you can remove the tether.
