If you tie the return lines on two different sized tanks together, one tank is going to fill faster than the other and you'll get overflow.

I'm not 100%, but i doubt this would happen. If the supply lines are tied together and the tanks are vented, then the fuel level would equilibrate once it got high enough.

So I confirmed that the fsv was doing just that, sucking from the front and returning to the rear. Looks like autozone has them for under $100, anything wrong with these???

Hmm. That sounds right. Well, now I wish I had done it. Would have saved me screwing with that damned FSV.
