Default Do I have to run a hobbs switch?
I'm running triple 465 walboro pumps, 1 all the time and 2 on the switch. Well the switch crapped out today at the track and almost cost me my motor so I'm thinking about ditching it. What are everyone's thoughts?

With 3 pumps I would definitely run a Hobbs switch. Don't want to heat the fuel up to much in casual driving.

Fuel will be getting pretty hot running 3 pumps all the time if not using the fuel.

about to say.

You say the "switch crapped out". What kind of switch, and how is/was it wired?

I'm running e85 and was running out of fuel at 1200 wheel so I added a 3rd. I'm running the Holley dominator so I think I'll switch to the pcm control for the added fuel pumps. Just found out yesterday that it was an option
