I got a new oil pump for the truck. Comes with 2 o- rings.

did you install it?

Customer reply replied 9 months ago
Not yet. I just bought it today. I plan on installing it Friday. I've read that it's easier to go through the timing cover than the dropping the oil pan. I still have to replace the o-ring to the pick up tube.
Customer reply replied 9 months ago
I've heard trying to remove the bolt from the oil pump is not any easy task.

it isn't easy . let me send you the instructions

Is there a harmonic balancer install tool?

there is but, the easiest way is to grease the inside of the balancer and the crankshafts shaft, and tap it on until its far enough on for the bolt
