I think this is the Walbro I intended to post for consideration:

Would one with this flow capacity cause return line restriction issues? there are walbro pumps with lower flow/capacity rates too.

Spend the money and buy a raptor, I've ran one on both of my cummins and they have been problem free so far with 50/50 blends, i have ran over 100 gallons of 50/50 threw my current one. cool thig is they have a built in bypass that is adjustable.
