        Loose pulley

        I got this to bypass a stock smog pump that was failing, I noticed that the pulley was loose on the hub. It jumps a rib on the belt every few days forcing me to reset the belt on the pulley. It was quite easy to install and looks great.

        5 1985 GT - smith4570 Installation Time: Afternoon


        I own 85 GT 5.0 Conv that said it was easyto swap the pump out after I got rid of all the hose! That said not having a book for smog replace it took a little more time for me to understand how the thing came apart, easy after you figure it out.. But than I would rather take my time & not ruin or brake somthing else, just me!! As usual Ford makes great parts! C Smith

        Air Pump Eliminator

        Air pump was starting to sound like a blender. I printed out a narrative on what to do with the two lines from the air pump. Job was simple. Used same belt that was on. Fit and quality was excellent, straight and true.

        4 1991 GT - 1FASTSTANG4U2C Installation Time: Less than 1 Hour

        Could not use part

        Unfortunately I couldn't use the part due to my car being supercharged and requiring an additional mounting hole the smog pump provided. However for non-blown cars it'd be an inexpensive power adder if you were trying to squeeze every possible pony out of your fox body. If your smog pump goes out and your mildly modded, this is definitely a bargain upgrade that'd compliment other mods like cold air induction, under drive pulleys, heads, MAF upgrade and intake swaps. Delivery time was superb and I kept the part in case I get another GT or a friend needs this part for their ride. Construction quality is great and durable.

        Smog pump eliminator for my mustang 87

        very nice and easy to install, sounds better now and i like it very much. it seems to be hard to do it but it is not, first uninstall the jonke one and that will give and idea how to install this one. very easy, very satisfy with this new idea.

        5 1990 GT - JayV Installation Time: Afternoon

        Fulfills its purpose.

        If you purchase this looking to add a significant performance increase you will be disappointed. However, your fox doesn't need to pass emissions so why keep the extra weight and strain of the smog pump on your car? Fits nicely and overall does exactly what I expected/wanted it to.

      • The Ford Performance Smog Pump Eliminator is designed for the 79-93 mustang 5.0, unfortunately it has not been tested for the F-150 variant of the 5.0.
