Be safe yes, but you might burn out fuel pumps quicker. That's a lot of voltage your pump istrying to keep pumping up, common ways jim and chris and rudel did their set up was using the evap line for the feed and using stock fuel line under car for return. And if u use in tank return its safe to not go into boost when your at almost 1\4 tank. You can get fuel cut off. Focuzed I think relocated his pump in the middle andstuffed the tank with a lot of foam to help with that.
