How did you do this?? did you just connect the Fuel supply lines together and the return lines together bypassing the selector valve altogether also known as the "dual function reservoir" With a couple of double sided barbs?

Yea but the line coming off the high pressure pump is a different diameter than the line into the selector valve. So I went to napa they had the right size fitting for the pump with the same diameter fuel line as the sending line and used brass fittings to hold the sending and return lines together.

They definetly didnt have a BETTER IDEA. Eventually ill buy a 38 gal fuel tank for the back and do away with the front tank.

You can only run one tank the way that I did it. Have you checked your pressure regulator and pumps?
