As I continue to plan out my build/updates, I've considered going to a surge tank in the front of the car to prevent and fuel starvation and/or be able to use the full 16.4 gallons (plus whatever is in the surge tank (IMG:style_emoticons/default/smile.gif) ).
My car probably won't ever see true slicks, but it still corners pretty hard, enough to slosh fuel away from the pickup I'm sure. I'm just curious if anyone else has ever felt the need for a surge tank in their cars, or has any particular tips/tricks before I begin my designs? Thanks! Happy race season.

Surge tanks are pretty easy to do.
SDS uses a simple tube with plates welded on and a few bung fittings, very simple very well thought out. Or you can do the rock crawler design which uses a filter much like the unit above. I had originally thought about using this on my car and have since gone back to SDS style unit. Gravity feed to the pump is always better than a suction feed. I am sure they both work well. I am just choosing not to go against a force of nature. SDS design Rock Crawlers Surge Tank built out of a fuel filter. You can increase the fuel filters surge tank capacity by using one of these kits. It even has a fuel petcock at the bottom of the filter to drain off water, or can be used a fuel sample port if you series requires that sort of thing. I figured in my case running E85 this would allow me to get some water out of the system. So my setup now goes like this: A - Stock Fuel Tank B - Pre Filter C - High Volume Low Pressure Fuel Pump D - Fuel Filter Water separator E - EFI Fule Pump F - Engine fuel injectors / Pressure regulator G - Fuel Surge tank Pretty simple, as along as I bring some fuel with me to the events, I can run ultra low fuel levels in the tank, 1-2 gallons and do my runs. That shaves 20 to 112 pounds of weight off the car! For an auto-x run well worth it! |
