Fuel Pumps And Surge Tanks

[maccattack]

Ok, I've read a number of threads regards fuel pumps and flow rates, in-tank, in-line etc. and the more info I get, the more confused I have become.

Here is the situation - I have just completed a rebuild which should see somewhere approaching 700bhp (flywheel). I currently have a standard GTR pump. I am about to install 700cc injectors. I do a reasonable amount of track work in the car.

From what I understand, there are not too many in-tank pumps that would support these horsepower numbers. Similarly, if they did, it could end up swirling the fuel and dragging air anyway, irresepctive of the surge potential.

I have been told I should go to a surge tank for the fuel and am looking at mounting one under the rear of the car (quieter and no fuel smell)

Questions are -

1. What size in tank pump should I be using for the lift.

2. What size in-line pump should then be used.

3. Who sells up-side-down surge tanks

Thanks all

1. The biggest you possibly can get. Having said that, most in-tank low pressure high volume pumps will easily flow enough to keep the surge tank full.

2. Bosch 044 or two smaller ones.

3. Make your own out of a bit of 4 inch stainless pipe, weld a top and bottom to it and put some fittings on.
