Electric fuel pump wiring.
 

This may be common information but here it goes. After searching my brain and then threads on this site I thought I should post this. I have wired up a few electric fuel pumps and I was a little shocked to read some of the ways members are wiring theirs. Toggle switches :ack:, direct and many other dangerous ways. Any electric fuel pump should always be wired through an oil pressure safety switch. Here is a link to a good diagram.

This has saved a couple of engines for me and lots of money too. No more toggle switches!
