Message: [QUOTE="madman1234509, post: 1177910, member: 3910"] I have stock rails.... There is no evidence of ported rails gaining anything, and a lot of people have actually had surging issues with them installed. Unfortunately adding a low pressure fuel system probably doesn't do anything for power. Unless your stock pump is tired and isn't feeding the hpfp adequately. If you can maintain rail pressure on a high tune, all you're doing by adding a pump that pumps more is just constantly recirculating more fuel. If you're not maintaining rail pressure on your highest tune, its probably because the hpfp can't maintain, not because your low pressure fuel system isn't supplying it with enough fuel. The only benefit I see from an aftermarket low pressure system with a stock hpfp is that you set the pressure to what you want and can monitor it with a gauge to make sure it's not draining pressure and starving the hpfp. With a stock pump you basically don't know until the truck doesn't start anymore because there is No way to monitor it and no codes that correlate to it. But ultimately it's going to be regulated down to what the fuel bowl is set at which is like 3psi +- a psi or two [/QUOTE]
