Lone Star "Make-Up" Tank
 

I worked on "Lone Star".
I have raced many Cobras.

I agree with the above statements, though I might add a "make-up" tank.

This item is used for racing, to provide the EFI pump with fuel under high "G's".

A/two lift pump(s) are used the get the fuel from the cell into a fuel reservoir that will feed your pre-filter.

The make-up tank has a return into the main tank from the top that allows air to escape from the fuel.

yep, a surge tank. Works great especially on a road course car.

What type of setup did you have?

I'm in the same boat here with EFI fuel system planning. The FAST fuel system design is just like "D". This requies lots of lines and fittings all over the place. I'd like to keep it clean if possible, so B or C look to be the best.

#10 line out of tank to 100 micron pre-filter, to pump to regulator to 1/2" hardline to front of car with 10 micron filter inline. Pre-filter, pump, and regulator are all at the rear of the car close to the tank. A high-flow "Y" at the rear of the motor with (2) #8 lines to rails. I added a crossover line to balance the rails at the front, but have run without it.

Wow that is close to the pipes....Well I guess I'll have a change of plans then based on this design. That's pretty slick there .... :hail:

Any issues with runnning such a short return vs a long return? Wouldn't a long return help cool the excess fuel to go back into the tank?

it's not near as close as it looks in that pic; probably 3-4" at closest, and I have the fire sleeve for insulation.

No issues with the short return for me; light years cooler than a front mounted regulator after the rails, with the super hot fuel coming back after being heated by the rails and engine compartment.
