this is suitable for a stripped lightweight track car... but of course unacceptable for a street driven vehicle, especially one that may be resold one day. If I were to convert my 370z to nothing but a dedicated track car, i might consider doing this. However, I feel that if you are willing to fabricate on the fuel tank, why not just simply open it up and solve the problem then seal it back together, retaining full capacity? A half-tank is kind of a thought-free solution if you just want the problem solved I suppose.

That combined with the colder temps and possible damp track makes me think I will be able to get through a session without fuel starving.
I will be buying the surge tank when I get some of my old race car stuff sold, which should be soon.
No rush, these will be available for a long time!

That is a difficult question for me. For as long as I have specialized in fuel systems, I have been opposed to fuel cells and never put much thought into them. My feelings are that a large container is a large container... and before I would fabricate all over my car to install a fuel cell, I would just open the stock fuel tank and simply solve the problems, then close it back up and re-install it. This allows you to also stay with the fuel in the factory location which is safer in collisions and better placement of the weight. The only way to use this location otherwise, is a completely custom fabricated fuel cell. But my feelings are still that there is already a fuel tank of the perfect shape for that location that came in the car from the factory, and simply needs a little thought and fabrication to clear up the issues.

A lot of tracks and racing organizations require you to have a bulkhead between the driving cabin and where the fuel is stored so building a fuel cell setup will require you to take that into account. CJM's design retains factory style plumbing, storage and pumps. It's the best solution out there for our platform, especially for those people wanting to keep the stock look and feel. There are plenty of other companies out there that make surge tanks and you can even design a custom setup for a reasonable price, but this product is specifically designed for the 370Z which makes it particularly attractive.

Yes sir. But do you know what you have to go through in dropping the tank?

lol, it's not that bad is it?

I mean, unplug everything, drop the drive shaft, unbolt it ??

As long as it's empty, not so big a deal is it?

You have to drop the rear subframe also.

Depending on how fluent you are, a tank can be dropped in about 45 minutes to an 1 hr. you do not have to drop the rear sub-frame.

Here is a rather descriptive thread. PM for more details

Thought free? Nice weight drop, puts weight on passenger side where I wanted it. 9 gallons more than enough for typical track session, clean look. Retains all stock fuel filler equipment and position. Allows me to put diff cooler in back with no net weight gain. For enthusiast it's pretty straight forward and why just for dedicated track car? I drive my car on the street. Yes you have to make determination about resale of car however if you have put a cage in your car etc its an option. It's not quite the same commitment as fuel cell.

If I had a dedicated race car I'd go for a fuel cell for sure. Stock tank isn't worth keeping regardless of what has been dropped into it to pump fuel. That's smart? Lol!

It's cool that we have variety of solutions. It's all good! Mines cheaper and simple minded though.

Yes that my overall take on it. I dont consider the method to be solving a problem so much as just throwing the problem out the window

The only value I see in it is the space gained to install other components. The point of fixing fuel starvation was because the community was complaining about having to stop and fill up the fuel tank all the time. Cutting overall capacity to less than half, and still not adding any fluid placement control to the remaining portion which means fuel starvation is still going to occur with probably 1.5-2 gallons left, doesnt sound like the solution... more of a serious compromise.

Let us know how well the fuel gauge works, with the missing sensor.

If you had a dedicated race car, what would your justification for installing a fuel cell be? Is it a rule/requirement in your sort of racing?
