EFI FUEL SUMP PUMP SYSTEM ?

Thanks just wondering if it would be worth the effort now I'll probably get grief about this on a couple of issues one it's for my 72 C10 and second already have a Tanks universal EFI so I'm ready for the on slot BUT WAIT I do have another ? on the return line since it just dups back into the tank with no restriction is it necessary to use high pressure hose like I said give me a hard time I deserve it
