Need a sanity check on my plan for fuel plumbing. I have a 22g RCI fuel cell mounted 1/2" over the tunnel, behind the seats in my caged baja. Just finished the tray fab, now moving onto the plumbing. The plan is to run 2 pumps in parallel for redundancy, switch on the dash to run either pump.
Top of the fuel cell
-10 AN fuel pick-up, reduce to -8 AN
½” hardline to the side of the fuel cell
Side of the fuel cell
100 micron filter & shut-off valve, reduce to -6 AN
Under the fuel cell (stock battery location)
Tee going to a (2) separate Carter rotary pumps, each with a 10 micron filter, check valve, then to another tee, then to a regulator mounted to the firewall.
My concern is that because it is a circle track fuel cell and has the pick-up top mounted, the pumps will not be able to adequately pull from the top of the tank and back down. I know most pumps are pushers, and only a few are good suckers. What do guys have for a fuel pump that run circle track fuel cells? |

IMO, you should be ok with the rotary pump setup as described.
I used a Carter rotary pump to empty my Eurovan fuel tank last week to facilitate a fuel pump change. I pumped out 11 gallons without any issues.
My understanding is, that the rotary pumps cannot lift more than two feet. If you are under that measurement, you should be ok. |

| the pumps are below the tank, and will syphon to the pumps after the line fills. I would put a shutoff before the pumps on top of the tank. otherwise if you spring a leek you have no way to stop it. |

| Thanks guys. Just needed some confidence before I start ordering fittings. I will post pics when I am done. |
