Fuel Surge Tank
Has anyone looked into one of these over an AUX fuel pump setup in order to avoid the fuel starvation issue with 800+hp and corners? Wondering if you could do the following -
1. Use the stock in-tank pump as the surge tanks lift pump by running switched power to the stock pump. 2. Intercept the FPCM and run one of the surge tank pumps in order to keep the ecu happy. 3. Second/third surge pump could be set up for an XDI belt pump etc. |

I have looked into it, the existing aux pumps and the dual pump hanger both create dangerous problems under 1/2 tank on track--I would never risk that. I have experience with this from my prior car, the only way I would build a high WHP ZL1 for track is with a fuel cell with a large integrated surge tank and dual high flow Walbro/Ti E85 pumps for both lift and the surge tank (dual on both). It's the most proven solution, and you can remove it as one unit and install in your next car.
Radium Engineering has a lot of universal Fuel Cell Surge Tank options for this, I'd start there. |

I am looking at getting a surge tank installed soon because I too am having fuel starvation issues on a particularly hard and long right hander on my formerly stock ZL1 on 2/3's of a tank of fuel or less.
(I've now bumped up the power slightly with intake, headers and a tune) Right now I'm about to look under the car for a suitable location for the surge tank because I think having it in the trunk would not be the safest idea.

Do you think a surge tank alone would be enough without the need for a fuel cell? (If I'm getting any of the terminology mixed up feel free to point that out as I'm not really sure how a fuel cell and a surge tank work together)

Keep an eye on Travis' thread and fueling issues... He's determined to figure this one out.

Not much room under the car for one, the only place I can see would be in the trunk.

I have an over the top surge tank set up. I didn’t like the radium because once you put 3 pumps in there isn’t much fuel volume.
The set up I have is a 4 dw350il pumps in 2 eBay surge tanks. I don’t remember the math but it is something like 2000hp worth of e85 for 15 seconds. I left the stock line in place and put a t under the car by the tank. I attached a 100hp jet to that t and then to the surge tanks. Basically I have 100hp worth of fuel filling the tanks at all times. I have no fueling issues and can run the tank as low as I like. It is busy looking but behind the trunk side cover so you can’t see it. I will find some pics.

Don’t laugh, told You it was busy looking. I will say I haven’t had to touch it since installing it. It seems to have clicked all the boxes. The extra pump only come on under load, 2 at a time.

For normal driving only the stock pump runs. You don’t have to do anything in the tank or mess with the controller. There isn’t a great deal of fuel circulating but there is a little.

Then I built a full fuel system off of the surge tanks up to the pi rails, I also tied the rails to the factory line up front just to be sure everything gets plenty of fuel. This means the regulator for the new fuel system had to be set above the pressure the factory system would produce to keep fuel from returning when normal driving.
