Actually, NAPA has an external, inline pump designed for such applications. I don't know off hand what an RE requires as far as fuel pressure, but we have P5000 and P5001 which are designed for an EFI or MPI engine in a non-FI vehicle. The P5000 is rated at 22-75 PSI and 50GPH. The P5001 is rated at 9-22 PSI and 50GPH.
edit: a quick trip thru my catalog here at home says the RE pump is rated 70 PSI and 60GPH...
