Let me tell you a little story about a aeromotive 340 drop in pump sucking my basket dry.

In 4th gear doing a log started at 3k and was ripping and when I got to 7700 rpms I sucked my basket dry (had a little over 1/4 tank) I leaned way the hell out, were talking 17:1 AFRs at 7700 rpm while wot. needless to say I'm lucky I have pistons inside my block still but here is a little mod I did to help fuel return to the basket.


I swiss cheesed the basket from the top down and left the bottom 3-4 inchs alone, so it still acts like a sump like it should. yes I went overkill but when you see 17:1 afrs you would too, I hope this helps anyone who has ran into this same issue.
 
How has this aged? I'm fighting a weird issue with only 4-5 holes of that same size near the bottom of the sump. Using a walbro 535 and only seeing fuel pressure drops below half tank. Only on DI and still in tuning phase
