These other fellas are telling you ideas that take some work but should absolutely work/solve the concern.
For me personally, before I got to the point of doing all that, I'd try your idea and then a simple relocate to behind the axle if that didn't help. That pump can lift fuel a bit - the question is how much under hot temps and when your demand is at its max. I'd make the easy changes and test it. But that's just my opinion.
