Educate me, please. I want to replace the stock 37 year old fuel pump & hotwire the new. Sometime will replace injectors & chip with stock or 42s. Car will not be raced. I'm into easy, so which pump should I get? Looking for one that is stronger (255LPH?) but also is a direct replacement as far as install. Ignorant about the hanger & sending unit. Do I need new, or will factory work? Same question about wiring. Just tell me "get this one" & I will. Thanks.
