Ron Francis Wiring, Complete Kit, MSD Atomic EFI Fuel Pump question

[Rodster]

Mike -
Thanks. I have similar replies from the Roadster guys. I will verify with a meter this weekend to be sure before doing any cutting. . .

Rodster, Mike is correct regarding clipping the tan wire and using the MSD Atomic to control the fuel pump. I have the exact setup you describe except i decided to go with a return system. Also, consider using the MSD Atomic to control the radiator fan. Im in the go cart stage and all these mods work well on my 351W.

Bob - Perfect Thank you. I am also running a return fuel line. And this is confirmed. I will pull the fuse for the fuel pump. Then I will cut the wire feeding the fuel pump line, and splice the MSD fuel pump wire onto the tan wire going to the fuel pump. This should retain the inertia switch.

Thanks also about the note on the fan, and I agree this is also my approach - use the MSD to control the cooling fans. I have some beefy relays for that. I will also add a toggle switch so I can manually turn the cooling fan on.
