Ok i know im going to sound like a complete pleb but i just want to check something silly on a cosworth as i seem to have confussed myself somewhere

what order from the fuel tank should the correct flow order be ie

fuel tank
fule pump
filter
fuel pressure regulator
fuel rail
injectors
fuel return
back to tank

or have i got the system
in the wrong order ....

i know that might sound like im being stupid but i just wanted someone to clarify
cheers ....

couldent find my cossy bible before i left for work tonigh ....

 

fuel tank
fuel pump
filter
fuel rail
injectors
fuel pressure regulator
fuel return
back to tank

 

cheers mate i got it in my head somewhere that it had to go to the regulator to regulate the amount of fuel used to the rail ... just confussed myself somewhere ...

ive got an msd 3.5 bar regulator and semines 55lb injectors,

is the msd 3.5 bar uprated over the standard regulator .
i heard somewhere that there the same as the standard one in a new case ...
thanks for your help fella

The only way you can really up rate a fuel reg is by making it flow more fuel, this is really only needed in multiple pump applications where the fuel pressure will increase if you cannot pass enough back to the tank.

Variable pressures don't really class as up rated,

The weber.reg we supply is as good as std which will flow enough for over 500bhp

So it depends as to why you think it's up rated or why it needs to be really
