Air pump eliminate?

So what’s involved with doing the air pump eliminate besides buying a $200 bracket.

You'll likely need a shorter serpentine belt as well. If your catalytic converter has the air inlet, you'll need to decide how you want to plug/cap it to prevent an exhaust leak there. Other than that, not too much other than fishing all the components out of the engine bay. I did this a few months ago with my son's 1990. Post with some detailed shots here:

The eliminator bracket doesn't need a shorter belt, it fits in place of the AIR.

You can leave the electrical connector hanging, and then use pipe plugs/caps to cover the AIR inlet on the exhaust manifold and main cat.

HOWEVER, the belt path with the pulley was definitely shorter than with the air pump in place and you can see in my pics where the tensioner bottomed out with the stock belt. Perhaps other kits better mimic the diameter and placement of the original air pump pulley.

Yep- make be gone. You and you car will not miss it. Buy the bracket and keep your belt. This is any easy, smart mod.

I used the cheap made in China Ebay kit the other week on my 1989. Fit fine with factory belt.

Spring for the TPIS kit if you can afford it though, support a good company.

Easy mod, should all just bolt on.

While watching Corvette Ben he simply opened up the air pump and removed the parts used to pump air.
Then you can remove all the AIR junk on the front of the engine and plug the old air inlets on the exhaust sustem.
