does anyone know if you can buy and install petrol fuel coolers??
they use them in heavy vehicle and common rail diesels but im guessing for safety reason maybe not in petrol.
I have also cleaned up my fuel economy a bit over the last week by changing the front pinion angles. the vibration I was getting out of the front end must of been labouring the engine also. even thought it was only at high speeds.
what are your thoughts??
