wish i would have read this sooner.....
take the pump back and go with a magnafuel.
we are running about the same motor set up.
i have 1/2" alum line to a magnafuel regulator (they have 2 outlets)
also run a magnafuel filter. best stuff on the market. (prostock cars run there stuff)
btw i do not work for or get any benifits for pushing magnafuel products.
the only issue is.... they are a little pricey.
i would also install a fuel cell
