My RAM decreases each year and bottle of wine. So it is in need of a new upgrade.
But if my 1150/30 sec pump spec, as per manual is not enough, I suspect I will need to upgrade pumps. In which case, what to? This is basically heading in the direction of the original query - trying to verify where I seem to be coming up short fuel wise.
What I haven't done yet is check each pump - with the pressure gauge between the two. From memory the pressure differential should be 1.5 - 2.0 bar. I am back at the car and my manuals in a couple of days so keen to try and resolve it then if possible.
But the only pump flow data I can find is as per manual which is 1150/30 sec before the FD (from memory) . I have 1400. If I need 1400 at the injectors (quite possible) I will need bigger pumps I suspect.
Regards
Alan
