Default Fuel Starvation with A Full Tank

I was running at the Central Divisions event this weekend at the Kansas Speedway. The car performed well overall, I was super happy to reports to the new oil pan I lost almost no oil! I did have one problem, after a hard left I would accelerate out of the corner and the car would just about die, I am pretty sure that I was loosing fuel. That being said during all runs I filled the tank completely in hopes I could prevent the loss but no luck.

I know that others have used a secondary pickup in the tank but I am having trouble trying to figure out the best way to set this up. If I can't find a good way to add a secondary pickup I will probably just throw in a secondary pickup.


Any suggestions would be appreciated.

Definitely my favorite choice but that costs points, well if I am reading the instruction correctly! It calls out a new pump is okay baring it is a replacement and not being used to supply additional fuel. This is my case I just need to fix the starvation issue but I did not want to risk getting call out. No that I have some real competition I want to keep everything on the straight and narrow.

I will take this to the officials and see what they say.

This is a known problem. It can result in power loss, the engine shutting down, and especially in forced induction applications, engine damage. Check out this review:

There's a solution available however:

I was to at just over 1/4 tank. In that video I made, notice the quick flick to the right after turn 6 onto the back straight? problem solved lol. I don't think it was costing me any time, but I would add a second pickup on the other side.

I'm running the SOS surge tank with my SCd F24. No starvation issues since. On slicks, I would starve on anything less than 3/4.

Same issue I've been dealing with. After about 15 minutes on my local course, I start getting fuel starve and the gauge will still display full... Until I turn off the car and turn the ignition back on. I've been filling my tank to the top of the filler tube to get as much time on track as I can. I want to add a surge, but do not really want an external system. I did have someone that was going to make me an in-tank version like they have, but that seems like a long shot.

I do not like the SOS tank because it replaced the charcoal canister and I'm guessing they just vent the fuel tank because of it. With E85, I prefer to keep the system closed to keep water absorption down.

We need to get together sometime dood.
