Sorry little bit of misinformation on my behalf, cars optioned with the dual pump setup have a low pressure "primer" pump in the tank and then a high pressure pump external.
Single pump setup is high pressure internal.
As for exactly what cars have what setup I am not sure as I have seen both V6 and V8 with the dual pump setup.
I thought it was standard on the V8's but seems I am incorrect.

My V8 Ute only has one pump in the tank, It's all do with the pressure on the fuel rail provided you have 280-320kPa rail pressure the injectors will squirt the programmed amount of fuel into the air intake and the motor will go.
V8 VN sedans (except SS) some had an optional 80l tank with an external pump, you can see this if you compare a SS to a V6 sedan. A 65l tank will still get you 400km on a tank more or less, it all depends on the right lead foot. |

The V8's have an extra low pressure pump external of the tank. Alot of people for go both pumps and go with a single bosch 040 or similar I believe. |

Cool I will do that test when I get it running thanks heaps. Thinking about it I beleave your right about being the same pump it only needs to have the right pressure in the rail as any more goes back to the tank |

I'm not sure myself, but it would surprise me if it's necessary to upgrade the fuel pump. Observation: I worked in a roadhouse that was some distance from anything like a Repco store. We routinely stocked parts for things that commonly go wrong. We had a type of electric fuel pump that was "universal;" it wasn't anything fancy like a Holley Blue, but would work on anything from a 1200cc Corolla engine through to a 360 Hemi V8. No harm in "test running" your present fuel pump, by letting it idle, then winding it up to about 3000rpm. If it splutters, you have your answer. Holden have always been big fans of universal tooling, parts that will fit on a multitude of models. |
