Bergs System HND1.2000ID Bergs II Dual System W/Tank Cap

"Currently unavailable" at review time. But the 2 hoses Assy is still available by itself and is good quality and works very well (also when using one generator only, thanks to the check valve in the quick connector). The tank is nothing more than a boat tank commonly available on Amazon, and you'll save money purchasing it separately. And you can also pick the best model for you....the one that came with my package is the worst possible (they are showing a different, much better one, now)! Still five starring it despite the poor tank choice as it did work very well. Great to be able to get through the whole night without a refill. Could also knock a star for very primitive support (almost non-existent, lucky if somebody picks up the phone...and gives you the time of the day if they do...maybe due to language proficiency?) . But hey, it worked great.

Some people said, in their reviews, that they had problems with cross-threading on the caps. I never saw that, but then I also screwed the caps on very carefully. (I always turn a cap backwards until it clicks and settles into the threads, after which I know I can confidently screw it forward with out messing up the threads.) I filled both Honda e2000 generators up, screwed on these caps (which entailed removing the tether on the Honda caps), made sure this tank was full. Then turned on the generators. I never had to remove any caps again for the two days we were dry camping. Of course, we didn't have the generators running all of the time, but I just turned them off and back on again. Worked perfectly. When I arrived home, I found that the tanks of the generators were so full that when I removed these caps, some gas actually spewed out (home is at about 100 ft and we were using the generators at a higher altitude). I'll mention that the tank became somewhat distorted at times due to air pressure changes. I just unscrewed the cap to relieve the pressure difference. Of course, this wasn't during use; that would break the seal.

I tried the extended run tank this past weekend. It worked like a charm with two e2000 generators. I didn't need to run both together for much of the weekend but did anyway to gauge how long I could go. I pulled out Monday morning and both generators were full and very little left in the extended run tank. I could have gone another night or two running both. Next time I'll only run dual generators on an "as needed" basis now that I'm comfortable with the whole operation. I packed an additional 5 gal. tank that I won't both with next trip. I was able to run the furnace, microwave, coffee pot, and satellite dish at the same time without any hiccups. Happy with the purchase.

Fuel Tanks caps will not fit on Honda EU2000i. The OEM and BERG caps are the same height. However, the OEM caps only have 4 threads up in the top of the cap's ID. The BERG caps are fully threaded. The end result is to use the BERG caps you wind up cutting threads in the EU2000i's tank using a large channel lock or pipe wrench. The caps that came in the kit, initially would not even engage the EU2000i's threads w/o cross-threading. Contacted IPI. They sent me new caps which still did not fit. The BERG caps have a sharp lip on the first thread that precludes the threads from engaging. The replacement caps that IPI sent were a little bit better but still would not screw down on the tank far enough to allow the gasket to seal on the tanks. I even tried grinding out the interfering lip. However, I could not get the cap to screw down far enough to allow the gasket to contact the tank w/o using a large wrench. I have had other aux system caps on my EU2000is and they fit well. I ended up ordering caps from another vendor. Hope they work w/o using a large wrench to get them on the tank. I bought some generator caps from a different vendor. They fit. The BERG caps have ~ twice as many threads in their caps. The non-BERG caps have their 4 threads up in the top of the cap by the gasket just like the OEM's Honda caps do. They also have the metal relieved where the BERG caps have all the extra threads. Now maybe I can try it to figure out all the other problems reported in the reviews.

I use this system on my Honda 2200 generator. Quality of all the fittings are great and work well. I just hooked it up this week and so far I’ve been running over 36 hours on a single generator. The only reason I gave four star rating instead of 5 is because the cap on the tank does not relieve pressure. The first time I hooked it up tanks swelled greatly, and it was leaking gas around the cap on generator. I purchased A cap that you could release the pressure on top. I’ll leave it slightly cracked and no more issues. overall is great except plan on buying you a new cap manual pressure relief for the gas tank!

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.

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.
