Is there anything special you need to do once its off like plug or cap anything or any tricks to removing?? Thanks

No tricks to removing the smog pump. Just unbolt the two bolts and cap off the smog tubes. You will need a shorter belt. I don't know what size because mine was off when I bought it.

Just did this on my 91LX. Just pull off the pump and plug all the lines. I pulled everything off I could, the pipe accross the back of the heads, the tubes and hoses and the vaccuum lines that were attached. I ended up plugging the remaining vaccuum lines and the tube off the x pipe with bolts and clamps.

Oh yeah and I used a 76" belt if I remember and I have A/C (for now).

Why are you removing it in ther first place? It's only worth 1-2 hp, and a replacement is $30 or less. Unless your heads won't allow AIR pipes, and you have no cats, I'd leave it on.

I am going to be adding the off road H pipe here real soon with the flowmaster 2 chamber kit! I just figured i would chuck it since it won't be doing much of anything anymore! And i was wondering if i could just weld where the tube connects to the h pipe and get rid of it completly instead of plugging the tube in the motor compartment?
