Default How to wire dual in-tanks?

How would i go about wiring up a dual intank setup for one to be constant while the other i can have wired to a switch up front when i want it on? I want to do this right and not mess anything up.

If your running a boost application, one way would be to use a heavy gauge wire powering the pumps off a relay. You could use a WOT switch like us Nitrous guys, and then have that trigger the relay to power the other pump. just a thought I had.
edit your intakes to in-tanks.

That was the whole reason I read this thread, I was expecting some tech questions about some radical project.

Cat3 was dead on though, you'll wire it up just like any other switched electrical component. You'll need a relay and some 12ga. wire or so (to split off for both pumps). You'll wire in the relay after the split, and inline with your secondary pump.

I was also wondering the same thing since I am still trying to decide to do 2 intanks or a seperate fuel cell?

Anyone know how long it takes to do a twin intank install?

a lot less time than a separate fuel cell.

depends if you are replacing the pressure or return lines, filter, rails, regulator etc.
