I simply would like to know if the 3300 is gravity fed or pump driven for the fuel delivery. I would like to add an auxiliary tank when camping since the approx 8 hour run time has me turn off, and restart multiple times throughout a weekend. I was looking at the Bergs System HND1.2000IS but this only works if the generator is pump driven.
Thank you for any information.

it’s gravity fed and you can add an auxiliary tank of course.

Is it possible to run the carburettor dry on a maxpeedingrods MXR3500 genset?
I recently purchased a 3500 watt version of your portable generator (47 pounds). The low speed function has failed and the generator seems to be over speeding. Also, the generator will not support the 3000 watts of power as advertised. What could be the problem?
I would also like a copy of the parts manual and the maintenance manual as well for repairs.
