I told you to run this because of the age and condition of your motor . It work well right ? The gauge on tanner's truck bugs us but its an electric and the pressure rises with rpm but it seems way low at idle for a motor with so few miles . I am going to hook up a mechanical today and see what it does . Cj says he runs 5-20 but I think thats a little thin , I run that in my 4.6 but most of my pushrod motors I run 30 or better .
