I got my walbro 255 pump off ebay brand new for 105 bucks. Do it right the first time trust me, I wouldnt buy a used fuel pump, especially from a car that has been sitting for who knows how long. As far as radiators, Im still using my stock 280z radiator, works fine for me. For a throttle cable I went to fred meyer and found a suitable bike brake cable and modified it to work. There is a lot you can do yourself, may take you a little more time but saves you money. So total cost for these three items.... Pump-$105 Cable-$7 Radiator-$0 just need a coolant pipe-$10. Total-$122
