Started looking at electric fuel pumps since my dual headers are too close.  First thought the Carter 4259 was better, but at $74 on Amazon.  A little research found that Carter took over Airtex. You can see on Airtex model listing pump at the bottom has same # as Carter.  There is a lower psi Airtex pump 8902 that might be a better fit, since Stromberg literature implies 3psi is preferable pressure.
