Seperate Swirl Pot

[Aussie Mike]

I reckon a bit of pressure in the surge tank is a good thing. I would even reccomend putting a restrictor in the return line to create a few PSI of possitive pressure in the surge tank.

The way I've got mine set up I have a #6 line from the in tank lift pump. This is a low pressure in tank pump from a VL commodore. I have a #6 return from the swirl pot but I've piece of brass in the line with a hole drilled in it to provide a bit of restriction. The feed from the swirl pot is a #8 line and it goes into the fuel filter and from the filter to the Bosch 044. There's a 1/2" line from the bosh 044 to the back of the left fuel rail and a crossover to the other rail. On the back of the right fuel rail there is a line to the regulator. The regulator bleeds off pressure to a #6 line back to the swirl pot.

There's also a check valve on the output of the 044 that stops fuel draining back trhu the pump when the car is sitting. It starts first turn of the key.

Here's a pic of the swirl pot looking from under the car (The pic is the wrong way round so it's a bit confusing)



The fuel lines running up the tunnel and you can see the reg on the firewall. the 3rd line is for the purge on the carbon canister.



Here's the fuel pump mounted on the underside of the boot floor. Not a position I would reccomend as the boot cavity makes the sound resonate even worse. You can see the check valve on the output.
