Smog pump/ Air pump

[Bedlinedf250]

I'm interested on clearing up some of my engine bay. I've seen threads on bypassing the smog pump and pulling out some of the tubes and hoses. I'm fortunate enough not to have to worry about emissions tests. Is their any benefit to keeping it or removing it. Thanks for the info

Other that removing clutter, not a lot of benefit. My understanding was it was for the Catalytic converter...which I suspect is prolly no longer on your truck anyway...

You might free up 1 or 2 horsepower.

Removes the chance of the air pump failing and burning up the belt. It also might remove the chance of an exhaust leak. Mine was leaking exhaust from the tube that ran between the back of the heads. Just required a different belt and a couple of bolts to plug off the ports on the back of the heads.

My cats are long gone. So my chances are is that some of those tubes are just dangling anyways. Also if I bypass the pulley do you know what size of belt. I'm not interested in power gain just less stuff in the way when working in the bay.

I have no clue on the belt...sorry.

Easiest thing for the belt is just run a piece of twine around your pulleys and measure the needed size.

I parked in from of the parts store with tools and tried different belts until I found one that just barely fit on. Took me about 15 minutes.

I went and looked at it today and unless I pull the pump it won't work they are in line of each other, or a dummy pulley might work. The engine is the 460, a different layout than the smaller engines.

They make a A/C pulley delete, maybe you can alter it to work for the air pump?
