Be aware that if the mechanical pump's diaphragm ruptures that electric pump will then pump fuel through the diaphragm into the crankcase. Which is why they should be on separate circuits!

If he put it after the mechanical pump, he wouldn't have a problem right? I think most of those click style fuel pumps can have fuel pushed through them.

It's plausible, just depends on the pump. Facet says "no" for the duralift but maybe other's are fine. Would be up to the manufacturer.

That's a good thought.

That looks workable, too.
You only get ONE chance to do it right the first time!
An isolated system is safe.
edit
doing the bypass and check valve setup is the best way possible to avoid issues imho...
However most of the **** pushed aint a fix for a moco mech. Pump.
My holley red dropped 2# of boost,causing a retime..
BUT my fawcett sucked pulling grades, my moco pump is on reserve!

I wonder if that's because of the pump or the filter that's equipped on the duralift. I'm thinking if you can pull fuel through it, you should be able to push fuel through it.
Facet does have a positive shut-off or anti-siphon feature on some pumps, so one would have to look at their specific model to be sure.
