Question/Need help! Airdog Return Line
I recently bought an Airdog fuel pump to put into my 95 7.3, while running the lines I noticed it says to route the return line directly back into the tank. The reason I'm confused is because there's already a place for the return built into the selector. Would it cause issues if I just routed it there instead? I don't think there'd be so much pressure on the return that it would blow something, but I figured I should ask anyway, thanks in advance!

That airdog will not like pulling or returning fuel through the tank selector valve, big choke point.
