I have noticed that the returm line from the fuel rail gets warm (heat soak in the rail) this goes back to the swirl pot that is constantly refreshed from the tank (cross over valves yada yada yada)
Question is that - is it advisable to fit a fuel cooler / radiator in the return from the fuel rail? Presumably cold fuel is better than hot?
I have heard that a lot of standard road going cars now have these fitted as standard to stop the whole fuel system heating up. I am led to believe these are normally mounted low down with a scoop to duct air into it and said to be used also to dissapate the heat generated by the HP pump.
So if a road car with say a 60 liter tank needs a cooler (1.6 litre engine returning reasonably small flow into a big volume) what hope of a 40 with 2 small tanks of 35 litres each?
Does anyone have fuel heating problems that is running EFI? If so how do you / did you plam on rectifying the problem?
Thanks
Ian
