I’ve been working on some items in the engine bay and lost track of where some hoses connect. I’m hoping that someone can help confirm the places where I marked as A in the picture are the same hose. Also, there is a hose coming out on the opposite side of the valve I marked as B. Does it go down and connect to a metal nipple that is sitting alone down in the area where I marked as B too? I cannot find a clear diagram of all the hoses. I added a picture of a surprise I found in the air filter housing while replacing the filter. I surprised to see all of that in there. I bought this truck and drive it straight to the shop I rent to work on it, but I noticed there wasn’t much acceleration. This is probably part of the reason.
