Ok, I converted an F250 to run WVO for a guy a couple years ago. I put the system he wanted on there, but advised it was not a good design. Long story short, his WVO supply dried up and he sold me the truck. I've converted it to an EFuel setup with 2 pumps. One for D2 and one for WVO. It's a much better design. I might post up some pics later. It's a truck I'm building for my son and I've read a lot of folks put the inertia switch in because of the electric fuel pumps tendency to pump fuel after a crash. The D2 pump is setup on a relay that relies on oil pressure to run longer than 20 seconds, but the WVO is not.
I bought an inertia switch off of a mustang. I plan to run it in the ground circuit for both fuel pump relays.QUESTION How sensitive should the inertia switch be? I can shake it a little and it trips off. It seems over sensitive and I don't want to have to reset it after every little bump?

 

My intertia switch is in the stock location (mounted on kick panel inside cab on passenger side) and I never had an issue with it tripping when it shouldn't
