I have a new in the box Melling oil Pump that I bought from Summit. I dont need it. It is for a 4.6 L 2 VALVE!. I took the back plate off of it to inspect the gears, the gear measured 12 mm thick. This is a great oil pump to replace the renown horrible ones from the factory. They are about $320 new, Id like to get $250 shipped. Saves you $70 + shipping. Let me know, thanks. 419-689-3648 -Brian
