    Default intank fuel pump

    This is good alternative and requires very little modification. All that is required is to shorten the bracket that the pump mounts in, about 12mm if I remember correctly. Just cut the two legs off at the upper part of the base, rotate the base about 15mm and reattach the legs. Also check the rubber connecter at the top of the pump they are usually split.

    you can also use a surge tank and the volvo pump that has an accumulator on it just like the 604 injection system

    the surge tank prevents the fuel pump from running dry when you corner on a low tank of fuel

    also using this method you don't need to worry about an in tank pump

    If you are using a surge tank wouldn't you still need two pumps, one to get the fuel out of the tank and into the surge tank and another to supply fuel to the engine, unless you can gravity feed it into the surge tank. This would not be possible on a 505. 604 I'm not sure. Is the accumulator you are talking about a scavenge pump separate but part of the main pump?

    Please correct me if I am wrong or let me know if I am on the right track.

    Thanks

    on a 604 it's easy as the tank is in the boot

    the accumulator on the volvo pumps keeps the pressure constant and also keeps the pressure in the lines when the car is not running and it is located right next to the main pump

    i put this post in to reply to ropes query

    What's the advantage of putting this in a 505?

    well, many years ago a mate of mine and myself converted a mitsu scorpion from carby to an injection system from a magna

    now then where as the car when low on fuel with a carb going through corners never picked up air from the tank enough to upset the carb it did so with the injection

    we placed a surge tank in the car and hence the car then always had fuel for the pump to keep the pressure in the fuel lines and injection system without the need of an in tank pump

    Probably a dumb question, but when you say a surge tank, do you mean replacing the main tank or is it a small separate tank?

    just an extra tank

    it only has to be fairly small but enough to keep the car going when the main pickup in the tank doesn't have any fuel to pick up

    we made a small alloy container that held around 1/2 a litre of fuel

    this little tank always stayed filled with fuel

    i think there were a few jap cars and even commodores around that had these little tanks as well from what we heard but we ended up making one
