Z1 Anti-Fuel Starvation Kit and Fuel Readings

Z is 4 ZEBRA! · 12-01-2023, 10:01 AM

Interesting. I had the same question to Z1 when I ordered the kit back in 2020. They said "the anti-starve kit acts like a surge tank and pulls fuel from the other side of the tank to fill the basket where the pump is housed. Eventually you will run the second pump dry but you would have to be quite literally on an empty tank to run the hydramat dry. If you street drive the car as well you can wire the secondary pump to a switch to only be used on the track."

No problems for me since the install, but I did install the CJM top hat at the same time.

I also recently got the Z1 kit installed. Also had some weird readings after a track event. I was assuming the lines could have moved in the tank and held up the reader. Took it back to the shop and they were able to fix it. I hope I dont see anymore issues moving forward.

They told me the lines had moved. So they zip tied it. Its reading fine so far. So hopefully it dont have any more issues.

I’m also having fuel level reading issues after I messed with the pump assembly. Gotta pull the pump assemblies out and zip tie things properly.
