Need a little help here please. Im running a 2002 WS6 with a 6.0 liter iron block and the STS rear mount turbo sitting at about 10 lbs boost. Its a daily driver but I like to play around every now and then. My question is fueling. I just replaced the fuel pump with the Wlbro 255 pump. The pressure at idle and crusing is around 50 psi. But if I step on it at all it drops to about 40. I have the SLIM 60 lb injectors. I was told that there are two different 255 fuel pumps a HIGH PRESSURE and a HIGH VOLUME pump. Which do I need for my application. And what should my target fuel pressure be.
Thanks guys
Thanks guys
Definitely need more pump....shouldn't see that drastic of a drop in pressure. Here is a sponsor that could help you out.

50# at idle is a sign of an improper pump install, defective regulator or an internal leak (if you used a kit with a rubber hose you may have found your problem).
Regrdless, I doubt 1 pump is enough for the setup you are describing. If I can be of help, please give me a call. I stock many components to build your fuel system & can help you with a design to fit your needs.
