just had a look in service manual read it wrong says 43psi standard i assume this is at idle, so is the preasure required to rise as the throtle is opened or is it a flat rate preasue and its all done by the injectors,

sorry to be dumb but this is my first real dabble into EFI

Thanks Tilly

Hi Tilly, the fuel pump will supply that pressure all day, regardless of how hard you hit the throttle, :-). How much is supplied to the injectors is controlled by the fuel pressure regulator, which will be somewhat less than the pump puts out, hence the reason for the return to tank fuel line. Hope that helps. Cheers Ray
