Does anyone know the SCCA/NASA TT rules for running a surge tank in the car? It seems like a lot of built race cars run surge tanks in the trunk area. Is it something as simple as requiring a full fire suit/shoes/gloves? Can the surge tank be mounted in the trunk box and sealed with a plate over the top? Trying to avoid removing the EVAP canister and messing with fuel vapor smell.

I have one mounted under the soft top, where the spare was, so you really do not see it. They never asked if I had one nor did I think to tell them I did...

I'm worried about tech and/or protest. I have the Radium kit that mounts almost in the same spot (opposite the spare tire area)...

NASA HPDE/TT tech is kind of on an honor system. A NASA racecar tech is more serious and they will probably require that it be sealed off from the driver's compartment before issuing you a yearly tech. Nobody in NASA TT is going to protest you over that. Again the NASA CCR and the tech form is more so to protect NASA from liability, and make sure that the liability is on YOU if something goes wrong.

Well, maybe I'll just run it as is with fire suits (good excuse to spend money on safety), and look into relocating/sealing into the trunk well or building a box around it in the off season.

Just remove the evap, extend the lines and place it under the car. I plan to install mine there but Honda Challenge rules do not allow them in s2000s yet.

Be sure your instructor or any passengers are aware of what you have done. I wouldn't get in any car with an aftermarket fuel system installed in the same compartment as I am in without a fire suit, underwear, gloves, shoes, mask, etc.

How are these not allowed in Honda Challenge...
7.2 Fuel Systems (all classes)
a) NASA CCR-Compliant fuel safety cells are allowed. Rear floor-pan may be modified to accommodate a fuel cell. If the fuel cell is not present, said opening must be covered with metal and sealed. b) Fuel lines and fuel pumps may be replaced with others of unrestricted origin

I would consider a surge tank a pump modification.
