i didnt have any problems with my std tank last time it was on the track but next time it goes out the car will have loads more grip and an extra 50bhp ish so im fitting one just incase lol. Im using the stock fiesta pump to feed the pot which should be more than enough and im using a facet sliver comp pump 5psi upto 200bhp to feed the engine which should be more than enough as im only look at 170bhp ish once i finsh/start the engine.
