does anyone know how good the stock fuel pump is for the xb? will it hold up for 7psi? whats recommended?

 

no need, i run 11psi stock pump. The limit to the fuel pump has only been exceeded by one individual (Leslie) and she mention 15psi on a t28 turbo was when it maxed out

 

awesome!!! are you runing the 11 psi with stock internals or upgradeed.....also,,,what is the safest psi to run with stock internals,,,do you know..


with an AEM F/I Controller.....do i need a rising rate fuel pressure regulator or an FMU or anything of the sort...my reson being is that before i found out about the AEM FIC i was going to use a Vortech Super fuel managment unit because i have one......any ideas???

 

^ you cannot do a fuel pressure regulator of any kind (returnless system), unless you fab a return fuel system..
anyway.. no need for that either

 

alright, so the xb doesnt have a return fuel line?.....thanks
