Hi everyone

So I just installed a in car fuel pressure gauge and upgrade my fuel pump to aem 340.

I made sure that i dropped the fuel assembly as far as the original one. The new pre-filter sits at the same location as it was originaly.

Every thing is good for about 100KM (20L) after a fill up.

after that if i launch the car hard the pump starves of fuel , i see a drop in fuel pressure and car misfires

So i am good for the first 20L only the next 40 are hell to drive.
