went the extra mile and set this generator up for remote fuel drafting as well..used a brass marine transfer valve to select between the onboard fuel tank or remote fuel via two hydraulic quick disconnects.
Made a bracket to hold the disconnects inside the fuel door

Then mounted the fuel fitting bracket inside the front area, inside the fuel door..plenty of room to insert a hand to make connections.

A steel front panel will cover all this area..I have some used 1/8"steel sheet back in the barn..haveta get it down off the rack and check dimensions..
Ice storm today this might be hazardous..100 things in the way just to get to that part of the rack..go figure
