The "Fed" tanks are different from the European tanks. The "Fed" tanks have a completely different venting system to work with our charcoal canisters to keep them CARB legal. The Proalloy or ATL tanks vent without a charcoal canister. The 05 has one discriminating valve and the 06 and up have 2 Discriminating valves. The 05 is added to the top of the tank and the 06 and up are put in before the tanks are welded shut. They also include a roll over valve on the vent as well as on the fill.

The fuel starve problem is on all tanks 05 and up. Except for the 211s that now have a redesigned tank. Unfortunately the new 211 tank will not work with our vent system. It is based on the none “Fed” design. The 211 does not have to comply to CARB standards.

The baffle design inside the tanks allows fuel to slosh away from the fuel pick up. I have several tanks, 05-08 and they all have the same design. From what I can tell it’s more the design of the baffle than the delaminating of the sealant. Oh, buy the way all the tanks that I have taken apart so far have had the sealant delaminated from the tank.

At best case the current tank will only maintain .366 gallons on the side with the fuel pump at a 1.0g left turn. Less with more G force (stickys). Of that .366 gallons, only a small portion is left under the fuel pick up.

As we all know it’s very bad to run an engine lean, even more so on SC cars. prolonged high G Left hand turns will starve the engine. There is no way around it with the current design with low fuel. The higher the Gs, the longer the LH turn and the lower the fuel level the more evident the problem becomes. Then add the delaminating of the sealant to the problem.

I am currently working on a design to the current tank that will drastically improve this problem and still be CARB legal. Should be available in a few weeks. Stay tuned.
