E36 fuel pumps

[V8mate]

The OEM part numbers for a fuel pump for a 323/328 is different to that fitted on the M3 Evo.

On Euro Car Parts, however, the parts numbers for the two vehicle types are the same.

Is there any difference on the OEM kit? Do the OEM M3 pumps have a higher flow rate?

[disco!!!!]

the M3 EVO pump runs at 5 bar, the non M pumps run at 3 bar

Brilliant, thanks

I want to fit a second pump to my 323's tank, so I'll just get another 323/328 one.

aye it doesnt have to be specifically from a 6 cylinder, it can be a pump from a 316i to a 328i
they are all the same
ive converted my 318iS to a 2.8 and im still using the 318iS fuel pump without issue

out of curiosity why are you wanting to fit a 2nd pump?

It's a track car and it suffers from fuel starvation when on long right-handers with a third or less fuel in the tank.

ahh ok
im assuming you would be wiring them up so they are both running at the same time
would you be fitting a larger return pipe to cope with the extra fuel going through?
