Added dual fuel pumps.

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

Only thing I see that I would do different, would be to NOT USE plastic
filters. I think that the metal ones are a safer choice. I have had the
plastic ones crack and leak.

Just realized how you mounted yours inboard of frame rail. Nice job. There has been discussions in the past on inboard/outboard of frame mounting. Both have good points. I put a rock guard in front of mine. Bob Dunahugh
