Two lift pumps or one?

Well, the new LP is installed. I still want to put a pusher in. Question is, do I keep both, one up front, and add one to frame near the tank, or put only one at the tank?

Would pressures be too high? I like the idea of redundancy, but what happens if one pump dies, would the other be able to pull/push fuel through the dead one? There are so many ideas out there and searched, but never found many answers except for maybe putting in a bypass around each pump. Guess I could just keep a spare LP in my truck and "plug" it into place if it dies. I am betting the rear pusher pump will last longer since it was designed to push rather than pull in the first place.

As far as fuel lines I will be adding new lines from tank to VP, trashing the banjos and getting AN type more than likely.

Thanks a lot!

Nick
