Hmmm, reading around that it MIGHT be a 20 AMP boost a pump, but it has a 30 amp fuse which is what a 40 amp would have. Im confused, but I know it's been on the car with an 03 Cobra tank & dual pumps with no issues for SEVERAL YEARS with a D1SC and a 76mm Turbo setup (recently made 547 rwhp and 615 rwtq with NO ISSUE).
