Im running a 3dr cossie on light blues on a standard pump im going to change the pump cos its the original one on the car is it worth fitting an 044 or keep it to the standard one im keeping it on the blues for the time being

As you have used the words "for the time being" fitting a 044, will give you a bit more bhp capacity before a change.

what PSI does the 044 run? I'm after a pump for the project..

standard is fine for stage 3, if going over 400 i would change to 044 for peace of mind

Std will fuel to 400bhp no problem, ther eis very little flow difference between 941 and 044, the 044 has a much higher lockout at 18amps, and 12L/min I think it is, got the graph somewhere.

Fuel pumps dont "Run PSI" as such, they supply a measured volume of fuel in any given time frame and generally supply less and less vaolume as the pressure they are asked to do so at increases. Here are some charts to explain.





Its important to note that the electrical current consumption increases with fuel pressure.
