Guys,

Is there any difference between the main tank and the Aux (Front) tank?

I noticed that the rear (main) tank has a bung plug in the top front left corner. The Birchaven did not use this access for the generator.

I would like to switch the tank locations and use the main tank in the front Aux position and utilize the top bung for the fuel return line.

Thanks for any thoughts and opinions.

But that gen bung pick up goes to about 1/4 way up from the bottom.  Not sure that matters.

Tom,

There is a difference that matters.  The vapor vent for the main tank is at the rear and the one for the auxiliary tank is at the front.

Thank you guys.

I may just weld a stainless bung to the top left corner of the Aux (Front) tank and install a tight shallow 90 degree fitting.
