WOW Bruce. Your photo is of mine. ( GRIN ) It's dead on perfect on how I did mine. Even down to the size of the aluminum mounting plate. I used steel lines on top of the tanks. Then hoses to the outside of the frame rail. Next those hoses were connected to clear filter that are connected to each pump. EZ to monitor/change. Then I connected a steel line to the steel line just inboard of the left front tire. ( For a carb. Attach to steel line on the frame to the engine.) ( EFI. Attach to TB. ) As to wiring. Use the original tank valve wire to power the relay. The Howell/GM system has the wire to the back for the pumps built into the harness. And is long enough. This setup can be used for Carb, or EFI. The only difference is pump pressures, and pump power source. Bob Dunahugh 78 Royale Iowa
