gas tank leaking

I have had this 2 years, I have run it 60 hours. The gas tank leaks where it bolts to the frame. It's a bad design or poor manufacturing, Not made in USA for sure. Too many models and design changes to keep track of in my opinion. Just trying to get the tank replaced has taken 6 calls, 3 emails, and still no results.

This unit has everything I need to keep the essentials of my home running during an outage!!!

This has been a great unit right out of the box. Easy to assemble, simple easy to read starting and usage instructions, portable and enough power to maintain my home in a safe and functional state during a power outage. Easy electric start for my wife if I am away on business. Great generator, bought 2 more for my children's homes.

Works just like is it supposed to.

Bought this almost a year ago, worked well, although I only had to use it the one time then. Power company trimmed all the trees over the lines last week, so I don't know if I will ever need it again. Glad to have the b/u though. I know it will work next time because it is a Generac

excelent portable generator.

Purchased this generator after Hurricane Michael. I used it to run refrigeration, medical equipment and my well. It had absolutely no problems carrying the load. It is a quiet generator and ran for about 14 hours on a tank of gas. I highly recommend this generator.

Comfort after the storm!

This product was a life saver for me and my family after surviving Hurricane Michael. It’s loud but it does it job and does it well. We were able to keep our house running for day without power. It runs about 10hrs on a tank of gas and it had enough power to run our whole home. Then after our power was restored it was used to help others until theirs was restored. This generator was a great investment, don’t be like my family and wait until you absolutely need it, buy one now and be prepared for anything!

No power :(

Well, I bought this a couple years ago to use when we go camping. I used it once and had no issues. Today I got it out to power my furnace in the house. None of the outlets have power. I checked the breakers and no luck. I tried the GFCI, but it won’t trip because of no power.

Hurricane Power source

During the recent power outage caused by Hurricane Sandy we used our GP7500E to power our entire home through a transfer switch. Refridgerators ( 2) , sump pump, Fan for gas heat, lighting, bathrooms , TV, kitchen appliances all working no problem. Unit ran 12-15 hours a day for 7 days. Changed oil at 32 hours then every 50 hours after that. Great unit. Purchased unit during the summer and this was the first big tryout. It passed with flying colors.

Runs rough right out of the box

This looks like a good unit. Easy to assemble and started up with no problems but ran very rough and stalled. Needed to call for service to come tune it up. Im sure its something minor like bad gaps in the plugs or something like that but a brand new unit should run for a few years before giving you problems. Don't know what this means for long term reliability.

2nd Generac portable.

I purchased my 1st Generac Portable, a 5 KW, 25 years ago. We lived in a suburb with frequent power outages. Since then we have relocated 4 times and it never failed me. The only problems were it was a "pull start" (I am 75 years old) and my power requirements have increased. I purchased another Generac. I wanted to stay with a winner. The 7500E powers my entire home, (and the air conditioning), and it starts at the flick of a switch. I gave the 5KW to a young fellow, a new home owner recently married. We had a power failure 2 weeks ago. Now instead of one happy Generac owner, there are two.
