3 thoughts on “Predator Generators Fuel Type, Capacity & Run Time Guide”
I’m trying to compare the predator 9500 inverter gas economy vs the predator 9000 generator out the predator 8750. However, the reviews compare them at 25% Power and the others at 50% Power. I’m just trying to find out which is more fuel efficient.
Is there a specific brand/type of fuel stabilizer that is recommended for the predator 3500 inverter generator? Plan to use it with our RV
Hi Matt- my 8750 petcock, likely common petcock on a number of models blew out the sealing ring (rivet broke on about the 5th time using it for a power outage, gas started pouring out of course and th engine shut down which alerted me. Was able to catch most with a gas can. I had all the parts and was able to secure it with JB Weld superglue 2800 (the one with the ultraviolet light, in the already on position until I can get another. Not sure if others have had this issue. I think it is cheap rivets holding the petcock on along the shaking.
