Fuel pump pressure and Walbro pumps


Member +
Hi everyone!

It's time for me to replace the fuel pump!
Is Walbro 255 reliable pumps? any good?

Also, I was always wondering is the fuel pump always have the same pressure no matter the engine load? or is it regulated by the FPR in any way?

Thank you in advance!

That pump is more than enough for what a 1.3 will ever handle.
The pump will push around 5.5bar @ 255l/m and then the FPR will make sure that fuel rail pressure sits at around 3bar constant(depends on car)
