The pump provides 4 psi to the Edelbrock carb, they would like 5.5 psi going to it and I was worried about not enough pressure. I have been using the truck on and off for a month now and today is the first time I have noticed this.
If I had been using the stock high pressure fuel pump that comes with the truck I could understand needing the return line because it would be providing more pressure than is needed but since mine is providing "less" than the manufacturer specifies then I did/do not see the need for the return line other than for what had happened to me today.

After thinking about it I am wondering if it is just because I had the key on today without the truck running while working on the electric windows.

I am trying to figure how the pump could fill the other tank and need to know where the pump is in the system.

Not sure where you are going with that, but I do understand - pressure = voltage and volume is amps.
Anyway, my searches are finding lots of people saying they run their electric fuel pump deadheaded. However, I'm not finding anyone saying how they run that particular pump - which appears to be the Carotor pump shown here. But, none of the links on that page explain how the pump should be used. So, for that I'd call Carter tomorrow if it was my pump.

higher psi = lower volume
lower psi = more volume
I've been a firefighter for over 20 years so I damn sure do understand the difference and I have just about had enough of your bull**** attitude throughout this whole thread. If you don't have anything constructive or helpful to add other than your condescending comments then please just ignore it and move on to someone else's thread.

The pump is after the switching valve so if it is pumping how would it back flow thru the switching valve to the other tank??
Now I can see if 1 tank was not vented and in the heat of the day the tank built up pressure and forced fuel into the other tank?
So guys how did the fuel get to the other tank?

OK guys tell me how with the way David has his system set up that the pump could put any thing from 1 tank to the other, dead headed or not??????

maverick, please re-think this, try and use a different tone of voice in your head when reading Jim's posts as I'm absolutely certain he isn't trying to be condescending or in any way less than helpful. Written text doesn't have the benefit of voice inflection or facial expression and it can be easy to misunderstand something written by somebody. But Jim is one of the best guys here and is only trying to help... so take a breather and read his posts using a different tone of voice/attitude in your head, OK? If you're still irked by his posts you may come across, you can add him to your Ignore List in your UserCP and you'll never see anything from him ever again.

I don't think it should backflow into the other tank. In fact, I don't think it should backflow at all. So, I'd call Carter's tech line and explain what is happening, how you have it set up, etc.
