You have the optional external tank setup, which I don’t have. I’d hook a tank to the black inlet line and let it rip, the on-board tank may be just decorative. As you noted, it’s not plumbed to be used. I have no idea what the fitting is on the inlet, if it’s the one used on the 1-30 you may be out of luck. I’ll peruse my literature for wise words on the fuel pump kit..
