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. (IMG:style_emoticons/default/driving.gif)

Good info guys, thank you.

Yep, in this setup, it'll be EFI. My plumbing idea thus far is actually
tank->
low pressure pump up front->
surge tank up front->low pressure line back through the tunnel->
high pressure external pump on lower firewall->
engine->
return to tank.

That still eliminates the long length of high pressure lines that Mark was alluding to, but also still allows me to stuff a type 4 back into the car if I had to. In this case, the low pressure pump would also be a "lift" pump up to the surge tank, and gravity/pressure within the sump would feed the fuel back to the high pressure pump.

In Chumpcar we don't need a fuel cell if the stock tank is retained, but I sure would like to go the fuel cell route, especially as it would make routing the water lines easier through the front bulkhead. Just need to save my pennies.

Shane, I have not heard of people using the snowmobile pickups, but that's the same concept as the Holley Hydramat (just cheaper). I HAVE heard of a cool one though - some folks use a large Yamaha marine fuel filter which also acts as a surge tank of sorts. Pretty cool idea. I think this is the one I heard them talking about.
