Bogging while drifting/turning hard on low tank

hey does anyone know how i can fix this problem(besides have a full tank) cuz it really bothers me sometimes and it does it if i have like a 1/4 tank to and i run on that and less all the time. Just wondering if there are any parts/uprades i can get to eliminate this cuz im sure it probly starves the engine a little while acclerating to?????

Dirty pre filter in the gas tank.

Pull the fuel pump assembly out and clean or replace the prefilter on the fuel pump.

BTW This has been covered quite a few times before.

Not unless you asked them too and infact that would make it worse if they flushed the tank and didn't replace the intank pre-filter

Pull back the carpet in the hatch, undo the plate on the fuel pump. Pull the assembly out and take off the old filter. Do the reverse to put it back together.

Its like a 10 minute job, to pull one out.

And you will just be starving the engine and overheating the fuel pump, so there won't be any real HP loss. No more than running out of fuel.

replacement filters can be found at many autoparts stores, or just soak it in acetone.

The fuel pump, pre-filter, low fuel sensor, and fuel gauge sender are all together in the tank.

no worse than running out of fuel a 1/4 tank early (which is what has been happening as far as the engine is concerned).
