Atomic rex does an intank conversion in the uk where they foam fill the tank and install a collector pot (has 3 trap doors so the collector pot is filled during acceleration and turning left and right) with a bosch fuel pump sat in the collector pot. whilst it wouldnt be financially feasible for them to send you a converted tank, they may be able to do it in kit form for you with instructions. I will try to dig out more info for you on one of the uk forums.

shamelessly cut and pasted from MRC- looks like they will do it as a kit.


We do the kit for this if you are interested??

You can buy the full kit from us
Fitted £867.17 + VAT (£997.25) + £50 deposit on sending us your tank
Parts £642.17 + VAT (£738.50)

This come with a collector pot, this is equivalent to a 2L swirl pot, and is filled under acceleration as well as cornering. There is a sock filter situated in the collector pot, and is piped into the internal Bosch 044 pump. And the return is piped back into the collector pot.

SO what comes with the kit:
Collector Pot
Internal Nitrile pipe both high and low pressure
Foam block
Foam inserts to fill tank
Bosch 044 Pump inc fittings
Aluminium bespoke Top plate
2 bespoke brass 90 degree fittings with Barbed ends for hose fittings.
Electrical seal
Wired kit
Top venting pipes and fittings
Fuel Level Probe correct ratings for standard Fuel gauge.

The fuel level probe needs to be changed as unless you want to put a mesh around the standard level the foam will prevent it reading accurately. If you don't want this, remove £135.68 + VAT (£156.03)

The motorsport one way valve fitted here is an extra £45 (£49.50)

It probably appears expensive, but with this system you are able to run the tank to below 10L of fuel, and there are no external swirl pots in the boot. Also as all items are in the fuel tank it is a lot safer. There are also no smells within the cabin you normally have with swirl pots.

Plus if you add the costs of putting together a system including fuel pumps, lines, swirl pot, fire guard, you will probably find the cost very similar.

The rules are pretty open other than a 5 gallon minimum and the fuel cell must be separated from the driver by a metal bulkhead. I don't see how a dry fit system would help at all; the problem is fuel starvation in high G left hand sweepers, not getting fuel into the car.

I'm leaning pretty heavily towards a modified stock tank, that way I can keep the fuel level sensor and stock fuel door for filling. I just haven't decided on a slice and dice or a larger in tank surge with some added baffling.

Thanks!

Personally, I would probably run a larger in tank surge tank. And then decide how much of the tank to remove. Also, adding baffling to limit how fast and far the fuel can transfer from side to side is something I am considering. I am sure the weight of the fuel sliding side to side has to have an ill effect somewhere when you are on the traction threshold.

Check out Big Al's fuel system, its the one I was referring to. He's running a small tank that has fuel flowing through it at all times using a low pressure pump. The high pressure pump takes fuel from the small tank and delivers it to the engine.

one small observation of the pictures I took, your friend (who's name I don't remember) that you were talking about not having his face in any pictures in your build thread on Rotary car club, his face shows up a few times in the pictures I took.

I'd hold on tight to that Solo Nats trophy. The club of SSM racers who beat both Eric S. & Andy M. seems pretty exclusive. Do you know any good rain dances?
