Stay away from a Holley pumps--without a return line they get hot and puke out. Mine lasted a year and a half. Go with a Mallory pump at the url below. It uses a different design than Holley and it does not have provisions for a return line. Mallory pumps come highly recommended on a lot of performance forums, and it is the one that is presently on my car.
