If you use the electric fuel pumps like Tracy is using what does the inlet side look like (plumbing)? Does the pump have any suction on the inlet?  Should it be purely gravity fed? Can the inlet be fed from a tube that goes into a tank close to the bottom 1.5" but is bent down in a 90 degree bend? The sump is lower than the tanks and the pumps would be at the level of the bottom of the sump. My concern is how much of a "hump" in the plumbing will the pump tolerate?  Thanks for any help.
