I run an electric because i HAVE to

If i had the choice, id go mechanical... hell of a lot more reliable... can buy one anywhere if you're on a trip and it dies

Typically a mechanical doesnt just fail...

To answer your question. 4-7psi if you dont want to run a regulator

I run a Magnafuel (about a 400 dollar pump. Way overkill for my applicaiton)

and i STILL carry a small clicker mr gasket pump incase it dies.
