As much as that at face value seems to be a plus, adding a considerable bit more plumbing, tank, wiring, etc, that still includes high pressure, in a area rather venerable in our older cars in even a minor shunt, seems to possibly offset that upside.
So you're saying it makes more sense to have the entire system from the rear of the car under high pressure than just the front-mounted sump !?!?!?!
Less plumbing than a full return system.
Wiring - to the front or to the rear - what's the difference?
The sump system is about as compact as any "in tank" system.
The installation of a sump versus any other efi pump system is just so much simpler and faster.
The sump just makes way more sense. You just need to find one that supports your HP. The Edelbrock one is pretty slick but makes no mention of what kind of HP is can support.
The front mounted sump solves some problems, I personally don't see a great problem with high pressure fuel lines running, correctly placed, front to back. Nearly every modern car has this set-up.
What I don't like is, with our older cars, with little designed in crush zones, the mounting of the sump system, that also has HIGH pressure, and more of concern to me, a quart plus of fuel, located basically where ever space allows, with little concern to accident impact intrusion, etc. The difference being, all this electrical hardware and fuel quantity, which does not exist in a rear fed High pressure system is now in the engine compartment, probably in front of the engine, with a lot of hot engine parts nearby. It is not a very forgiving location, and still being fed by a rear mounted low pressure pump rated likely at a slightly higher gpm flow rate then the sump pump.
It would be the location and mounting lack of concern that gets my attention. It is a solution that I would consider, and aim one of the in car extinguisher fire nozzles at.
