After a six-month hiatus, we've rounded up all the parts needed to tackle the high-pressure fuel system on our 2008 Ford F-250 6.4L Power Stroke.After a six-month hiatus, we've rounded up all the parts needed to tackle the high-pressure fuel system on our 6.4L Power Stroke. In order for the 2008 Ford F-250 to make the 900-rwhp number we want to see, we'll be calling on a set of 100-percent nozzles to get us there. However, knowing that without the ability to maintain adequate rail pressure our horsepower goal would be unreachable, we're also employing two high-pressure fuel pumps. This combination of parts has proven capable of making 1,200 hp and has propelled the Rudy's Diesel Performance Pro Street truck to 9-second quarter-mile times.
