    The S/c VX Fuel pump unit is called a MRA which is fuel pump and fuel level sender together in the one module. This is linked up with a fuel pump controller in the supercharge models.

    What is it you want to know ?

    The s/c pump is a roller-vane type and produces a higher pressure and litres per minute than the standard n/a pump. I know a few people now who have fitted these pumps and not worried about the controller. Wiring them up the same as a n/a pump just has them working at the higher speed all the time. Which doesn't seem to be a problem as the extra fuel just bypasses back to tank anyway. Two guys I know of just ran with their standard n/a pumps with a super6 conversion until they could change them to something bigger at a later date. The LS1 VY ute runs the same controller onto a centrifigul-turbine type pump which btw is the same type as the V6's run (Centrifigul-turbine).

    Depends on which model too I suppose.
    The VY can have three differences:

    V6 engine......350kpa, 1.7 L/min @ 13.5 volts, current draw 7.4 Amps maximum.

    V6 Supercharged engine......410kpa, 3.2 L/min @ 13.5 volts, current draw 18.0 Amps maximum.

    V8 engine .......400kpa, 2.5 L/min @ 13.5 volts, current draw 9.6 Amps maximum.

    Well if its for a L67 s/c V6 conversions I would just use the In tank S/c fuel pump assembley. You can even buy the controller if you can be bothered and work out how to wire that in. ( I wouldn't bother though ) Then you always could go surge tank and say a bosch in line pump but the Holden in tank would be less hassles.

    What was it again a sedan ? What model ?

    I have a L67 s/c V6 in a Torana and i used a VN V8 internal fuel pump in a VN fuel tank feeding to a VL turbo high pressure external pump. No controller and it works a treat!

    Yeah the two speed set up of the s/c fuel pump was mainly there for in tank emission reasons and also helped keep the fuel cooler in tank. As the fuel was not continueously returning to tank at high pressure / flow stirring up the fuel in tank and warming it as well. This would create a bit more in tank emmissions so they gave it a slow speed setting for when the extra fuel wasn't needed.

    Controversial input here :D

    Just use your stock pump, will supply up to 200RWKW reliably and safely! Will be a while before your L67 gets anywhere near that kw on wheels unless you are dumping a lot of FIT bits onto it as well.

    No you are right as I know of two guys who have slotted stock L67's into their cars and are still using the stock n/a fuel set up.:thumbsup:

    Another option is the Walbro GSS341 fuel pump, this is an in tank replacement rated at 2.8L/m and can be had for approx $180.

    Is that a replacement for a sedan full tank in tank pump ?

    what I'm getting at is the ute and sedan pumps are different due to different tank shapes etc.

    Really? Just Google a unit converter. 410kpa is 59.5psi according to the Google conversion.
