We dont run the arch liners, but yes I took the front bump and the slam panel off.
(there are 2 bolts that arent obvious on the slam panel by the way, on the vertical bracket, not just the 4 at the top)
When you take the pump itself out, remember there is a 4 bolt holding it in which is tucked around the back, and also the high pressure pipe bolts to the block under the inlet manifold.
