I have a new electric fuel pump I got from Ames (?) last summer for like $35. Not sure what size line it takes. If you're interested I can dig it up. Make me an offer. Never used.
As a side note - the electric pumps like to "push" fuel, rather than "pull", so it's best to mount near the fuel tank, as I understand it.
