How To know What Fuel Pump I should use
My BMW 530i was working normally until I changed my fuel pump. I forget to
keep my old fuel pump and the new one doesn't work successfully. I changed
the computer of it and the fuel hoses starts to burst.
How can I know what version of computer, fuel regulator and fuel pump should
I use for my BMW 530i. My BMW is of type 520i and I replaced it to 530i.
I changed the engine from 4 cylinders to 6 cylinders.
