I removed the existing 5/16 line from the tank with 3/8 steel line (still mounted on the rail but not used for some reason, probably a quick fix to install an electric fuel pump), ran steel line from the pump to the in line filter, elevating the fuel line away from the block.

The existing 5/16 line was connected to a disconnected in line electric fuel pump....

I'm sure that didn't restrict the flow!
The line out of the main tank under the truck was cracked at the clamp so I replaced it also.
Fuel supply should be all good now! Just waiting on that spacer I ordered.
