Two fuel tanks to one

I was clearing the fuel tank hose situation under the jocky seat. There was 2 protable 12 liter tanks hosed directly into the fuel line into the motor. I thought i would like to remove these tanks to fill them. so i bought connectors and made the hose with the coupling single so i dont run down 2 tanks instead change tanks when one is empty.

I havent ran it yet but im having a sneeky suspision that it might be like that for a reason. The engine is a 75hp. Will a 75 motor sucking out of a 6gallon tank with a connector starve?

Any advice?

Thanks in advance

My old 100 hp, rather thirsty Mercury, seems to be quite satisfied with portable 22l tanks and quick-connects, one at a time.

Hi Darren
I have two 22ltr tanks under the seat with one fuel line, I change over when the first tank gets to 1/4 full and my 75 yam runs sweet.

Merc 60 1979ish, 2 x 30L +1 x 22L tanks, i swap the hose when it coughs & dies. Simple. Easy. Spare hose solves most faults.
