I just bought a 38mm weber carb and a header for my stock 22r and was wondering what I should do for the fuel delivery? I have a fuel tank out of a EFI 22re with the built in fuel pump that is hooked up for a back up along with mechanical pump. Is the stock mechanical pump going to put out enougth volume and correct 3psi for the weber? Or should I use the electric pump with a regulator? I am leaning towards to electric pump with a reg. Anyone have any other ideas or opinions?
