I have taken my Zcar mini vtec to brands on Friday and was suffering from hesitation coming out of corners (mostly the 2 left hand bends). It is not possible to replicate any issues in a straight line or on rolling road. I filled the tank to the brim and still suffered the same problem. Is it possible for fuel to starve even on full tank and has anyone ever experienced this. My fuel tank looks to be standard set up:

Ktm the car is off the road at the moment and in storage having some work done. Will take another look at it when its back

Somethings to note - fuel pressure stays at steady 2.7 bar and regulator is on the return line at the front right by the tank

If your pressure is staying constant then I would be changing yout thoughts on the cause of the problem.

I would look at an electrical problem.

I can see you regulator in picture, I have mine in back next to fuel rail. agree with Nicklouse, if your pressure is not dropping, then 9 times out of 10 it will not be fuel,
