The return line on the injection tanks returns close to the pick up point of the pump. This generates vortexes to circulate and promote convection of the fuel in the tank thereby maintaining a more constant fuel supply temp. Make sure you use good tight fitting hoses on these tanks as the pump can supply up to 30 psi or more depending on regulator setting.

Plumbing the return line on non injection tanks back into the pump feed promotes increases in fuel temp at the carb.

What sort of temp increases have you seen dude? or is it just something that you've read about?

Just wondered because i'd have thought that the 2 copper fuel pipes running the length of the car would help cool it down. I personally wouldn't have thought it'd matter either way anyway seeing as the carb is sat about an inch above the fecking hot turbo in a hot engine bay...

I would have thought this doesnt matter as long as the fueling is set up on the rollers, as the loss in fuel density can be solved by giving it more fuel volume?

sorry for a bit of a newbie turbo question but...why do you need a return on the fuel tank, even if your using a carb???

The return to the tank is from the fuel pressure reg, not the carb.
