If its a 5.0 liter than I can help. Dont know shit about the modular motors though. On a 5.0 there are so many routes to take as far as fuel delivery and it is very, very important. Let me know exactly the year and setup, heads, intake, pumps, fmu or not, and we will go from there.

A typical setup would be at least a 190lph intank pump and an inline or t-rex pump. People will tell you that you dont need both but I think you do. Fuel, fuel, fuel. Dont starve that thing or bang!!!

To me it seems like your set up is all wrong fuel delivery wise. Your using 24# injectors on a motor that is more than capable of 425 RWHP??? You need at least 36#ers if not 42#. Then get a real pump like 255lph and trash that FMU. Just make sure you have a boost sensitive regulator. Is your air meter calibrated for your 24'S?

This pump should work fine to solve your fuel delivery problems. Your still gonna need to get rid of that FMU and get a Kirbad adjustable regulator to go on the stock rails and no smaller thatr 36# injectors. The 24's will never support your kind of power. Call me (510) 760-5254 when you wanna come to get the pump of to set it up.
