Fuel starvation, who else?

I am still looking for them to push it harder, but so far it has done its job to the level where we feel comfortable getting started off on a production batch of them. Aside from functionality, I was looking for confirmation on fitment and complete function of the level sensor setup and everything, and there have been no issues with that either.

What was reported to me was that over the weekend they ran the car on a track with a heavy right that would always give them trouble anywhere below 3/4 tank. He said they ran the car down to 1/2 tank and experienced no issues.

In the situation of this product, if it works at any tank level, it will work at all tank levels. However, I still want them to test it more and bring it to lower tank levels because at lower tank levels it will effect what we are calling "recovery time".

I want to make sure that with even less fuel available to the factory pump assembly to send to our surge can, that the setup continues to work without any noticable fuel pressure drops. While we already know now that this product is definitely helping, I was looking to not only "help" this problem, but completely murder it. I want to hear that this is allowing you guys to run the cars to 1/4 tank or below.

when i instructed them how to plumb it, it was one of two plumbing maps that we have. it was the more simple one. This more simple configuration doesnt use one of the ports, we had them block it off. But that extra port is needed for the more complex plumbing map. While we believe the more complex map will offer greater functionality of the product, we also feel that it introduces more dynamic situations where a balance could possibly be disrupted causing a bizarre situation. It may not be possible to make it happen, but we dont know without trying that plumbing setup. We wanted to try the simple setup first because we figured it may actually work well enough that the more complex plumbing arrangement wouldnt even be needed. The first production batch will keep that extra port to block off... but if we find that nobody needs to try the complex plumbing map, we will end up just eliminating that port in production.

We are going to start gearing up to build a large batch of these shortly now. We have a couple things to finish up in the CNC and then we should be able to start. I am confident enough now that if any problems should arrise from this point forward, it would be resolveable within adjustments to the plumbing.
