Firman T07571 7500W/9400W Electric Start 50A Tri-Fuel Gas Propane Natural Gas Generator Manufacturer RFB
Very happy with this generator. If it was used you certainly couldn't tell it. Not a scratch or mark on it. Ran it on LP and runs great. Powered my whole house when the power went out for awhile. Excellent customer service,they worked with me to have it shipped to a Commercial Business. Shipped Quickly. Thanks for a Great Tri-Fuel Generator at a Good Price.
Looking for a 20ft - 25ft 3/8 flex hose for NG. I don't plan on ever using it with any other fuels. Had NG with quick disconnect line installed to inside garage door. Safety code says it needs to be 20ft from structure.
Nobody offers longer then 15ft unless 3/4 " .
Please advise
I have not used it yet. It is for emergency power loss and projects around the Farm.
The generator works and runs like a champ!!!
