Little Update on the truck. Got the exhaust manifold welded up, and all unnecessary hoses taken out. One last thing is a question on the charcoal canister, can I removed these last lines that come from the fuel tank and front diff?

The front differential vent needs to stay. The line to the tank is the vent for your fuel tank(s). If you remove the canister, you may get some fuel odors.

Can I get a vent that sits right where it comes out of the diff? And can I remove the fuel vent and relocate it closer to the tank? No big deal on either of them being where they are, just noticed them.

You want the diff vent as high up as possible, to keep moisture from entering.

Can you confirm what belts are needed for this?

The only non-stock belt needed is for the alternator. I posted a Dayco # somewhere near the start of the thread.

You can remove both pumps, the associated hoses and also the secondary charcoal canister if it's still there. Replace the alternator belt with Dayco# 5060530.

Here it is @txaggie
