My lift pump went out on me last sat. I drove the truck about 5 hrs with low psi. I had like 11k on the flat and would drop down to like 3k on big hills. I did my best to keep the psi up I slowed to like 30 mph to keep psi up.
My question is what do I do to check the cp3 to see if its bad? Do I just put the air dog on and check my rp?
Thanks
