Quick question.... Has anyone ever used 2 stock honda fuel pumps together? Meaning one intank, and one inline? Would this handle 12psi on 450cc denso injectors?

 

Well, no I have not. But I have seen two stock Honda fuel pump use side by side in side the tank. You need some custom work to get it done, and you also need to upgrade the fuel pump electrical line and fuse. FYI, that guy made 405 WHP at 18 psi in a fully built b18c.

 

Too much work, buy a walbro hphv intank and you'll be good well into the 400whp range, and some guys on this board have pushed them in to the 500whp range.

 

i don't think ghetto and forced induction mix well. The cost of doing what you suggest costs more than just buying a walbro pump

 

Not if you have a pile of stock honda fuel pumps your friends though out for junk for walbros.. Its about volume, not psi.. 2 pumps =

My friends buick GN uses two Modded walbro 255's !!!! One runs all the time, and the other kicks on under boost via a hobbs switch.
