Hi I could use some help. I have a 2002 gt no fuel pressure at rail at all.When i press Schrader after turning the key i get no pressure at all. Can hear a faint hum from pump but not loading up my rail. So after lowering the tank i see that the tank is a 2003 cobra tank. I need a new pump for about 450 hp supercharged 4.6l 2v with intercooler,kenne bell bap 42lb injectors.Any recommendations on good replacement pumps.Your help would be great. Thanks.
