Rx7 Fd3s, fuel missing at high speed left corner

Hi guys, I've a fully tuned 1993 RX7 Fd3s, I found that in high speed cornering (corner on the left), for few seconds fuel miss (than makes a bang from the exhaust)...
does someone know if there are some easy mods to modyfy the tank to help the fuel pump to be always full?

that's my Rx7

Best Regards
Ludovico

Looking good!

I'm assuming you're going to need some sort of custom fuel baffle in the fuel tank.

Keep the tank FULL.

Nice car!

Seriously though, that does not sound right, have you looked inside the tank to see if it looks stock or if anything is missing/displaced in there?

You need an anti-surge system. Hyperion makes them. Check them out: https://www.rx7club.com/vendor-class...tem-fd-877845/

I have one on my FD and I can run my car hard on the track with 1/4 tank of gas without any issues. His product works great and is very easy to install.
