Ok everyone I need help I have putting headers on my 2002 F150 4.6l and I’m wanting to change my EGR line as well but when I look up that part is says I need a engine tag or the vin normally I would use the vin but before I became the owner of this truck my buddy had it and he put a motor from a different vehicle in it. Now I know that he put the same 4.6l motor in it but the EGR line I found using the vin looks a little different then the one on the truck now so if I could get some help on where the location of the engine tag is that would be great.
