You are the man! Thanks for breaking it down for me!

No problem.. thanks for posting those pics. I saved them and I will use them to create an additional pinout for future installers.

Awesome! I'll post some more pictures when I have it finished and let me know if there are any other pictures you need while I have everything out.

For anyone else trying to feed the new 6an line up through the bottom of the tank, I fished some 14ga wire down from the top, tied it to the 90* fitting and use that to help pull the new line up.

I see quite a few posts regarding the venturi system, and to be honest, I only started learning about the venturi system while investigating the fuel starvation issue.

Is the venturi system considered a wear item? Would a new fuel pump assembly create a stronger venturi flow, mitigating starvation? I'm debating between replacing the fuel pump assembly vs going with the aftermarket setup. The car does see regular track time.

The venturi system is not a wear item. I tend to call them "solid state" devices, though I don't think the term is applicable, it just sounds intuitive in my head to describe it. There are no moving parts, the only potential wear would be erosion, and I am guessing none of us will live long enough to see it in our venturi. Debris could very easily clog one, as they have pinhole sized orifices'. But, they are fed only post-filter fuel (with a stock fuel system, no promises its being filtered with DIY custom setups).

I am pretty close to pulling the trigger on another accessory for our twin pump hanger that would add a filter and regulator to it, so that it could be used a direct replacement to the entire stock sending unit and not even require a return system to use it. This accessory might be the only thing I am currently missing to truly have something for everyone again in regards to the fuel system.

Hi Phunk,

Oh man, I need to find how to adjust notification settings because I didn't see that you had replied so quickly until now after manually checking the threads I've replied to.

I'm connecting the dots together and I realize you and I were just emailing each other. I didn't know you are THE Charles :).

I think a filter/regulator accessory would be great considering the twin pump can only be used with a return setup, and since I'm in California, I'm not confident the return setup will be a carb legal solution LOL. I do have the anti fuel starvation kit and I need to dig back into the tank and optimize it because I'm not confident it's working... I'm at my wits end trying to understand why it's so hard for manufacturers to prevent the issue. what happened to the days of tank welded metal baskets?

I think if the Twin Pump / Canister Kit can be used with the factory setup, I think it would be easier to justify it for track junkies like myself that isn't (yet) after big power, battling starvation, all while trying to remain carb legal.

My fuel hat finally snapped in turn 1 at thunderhill west, just checking in on this fuel canister accessory kit we talked about for the stock fuel system :).
