Hmmm ... I'm intrigued. I may buy one to experiment with.
Low pressure fuel systems (mostly engine driven pumps) don't usually need a return line. (Float needle valves are usually enough to resist fuel line pressure in low pressure systems.)
One of the problems with in-tank and inline fuel pumps (close to the tank) is how to get the electric pumps turned off in an accident. (Pusher pumps, versus suckers, are almost always better.)
At CarQuest, I often cautioned customers buying aftermarket electric inline fuel pumps. Especially if they appeared hellbent on a "bigger is better" approach.
The filter's return line may partially alleviate fire risk. Return line won't do much for a fuel line fracture or break but there is a potential for minimizing risk.
