RE: Multiple fuel tank hookup - series/parallel?
If you go parallel make sure the vent and fuel lines going to your Tee's are the exact same length... Equal pressure will garentee a even fuel burn from both tanks. Works great for me !!!.
Good luck

P.S. The tube length needs to be the same for the vents, and the two fuel lines need to be the same.. The fuel / vent tubes don't need to be the same with each other..
