i am doing my research here for a custom kit and have a question regarding fuel pumps. what is the threshold psi for which i will need to upgrade my stock fuel pump to a walbro? some people say 6psi, others say 10psi.

thanks in advance.

depends on what kind of fuel system you are running, little more info please. AFC hack, fmu, hondata?

 

will you have aftermarket injectors? or just add'l ones? I'm not sure on what psi, but I know for my setup, fmax at 9psi, with 2 add'l injectors, stock wont hold up for very long. I have the ERL MF2 injector controller. If you can just get the fuel pump. in best buys forum walbro 255lph for $89 shipped is a great deal!! Just also make sure you have a fuel pressure regulator that can handle the extra load.

 

i am going to be running 440 or 450's with the vafc hack. i know the pump is not that expensive, but i want to know why i am buying the parts, ie if i really need the parts.
thanks.

 

Personally I would get the pump in case you want to up the boost or you spike or something. But I know people that run 6psi with that set up and dont have any problems. I wouldnt go over that though.

 

thanks. any other advice on this topic before it dies?
