Alright I don't wanna hear it doesn't add performance blah, blah, blah. I've tried to bypass mine w/ a shorter belt and ended up with either too short or too long. I know they sell kits for Mustangs to eliminate the air pump. Does anyone know if they work on trucks? Mine is a '93 F-150 w/ 5.8

 

I tried the same thing on my 96, 302, couldn't find a belt either. Not sure about the stang smog pump eliminator. I would guess no, since I had to buy new accesory brackets when puting 351 in my stang, I dont think the smog pump brackets would interchange.

 

a man my truck is a 93 f-150 with 351 also. my air pump is eiminated if you wantg me to i will look at the belt configuration and send you the belt size and the routing. just send me a e-mail address or i will send it over this.

 

Hey Pro,
Please post your belt size here, so others of us that are doing the same thing can benefit as well. I'll be getting a new belt in the next couple weeks.

 

Oh please post that info, I would really appreciate it and it looks like some of the other guys here could use the info. I would owe you a big fav.

 

I just removed the smog pump from my 95 Lightning with a smog pump delete pulley from Jegs for a 87-93 Mustang. I have small underdrive crank pulley also a 97" belt was used but you have to work to get it on so a 98" would fit better.

My 2 cents.......

Jegs #778-68110 Proform brand,$55 bucks!

 

I have a 97 f350 with bad air pump. Am i correct in my reading on here that i can bypass the air pump? Can i just use a shorter belt? what size?

thanks.

 

yes you can use the mustang eliminator, the one for 94-95 stang works better

 

I would like to know if a smog pump elliminator kit for a 93 5.8 mustang would work on my 93 5.8 bronco or should I install a smaller belt. If so, what size sould I use?

 

I also run a shorter belt on my '95 5.0. Tried several brands at the same length and the Gates brand worked. Not sure if same belt is used on 5.8. There was a diff in length although they both said same thing on markings. I used a belt measurer to concur there is a differences in lengths amongst brands.

I'm sure you guys know this, but for those that might not:

If you eliminate the air pump, you MUST eliminate the cats.
You can have an air pump without cats, although it is a huge waste, but you cannot have cats without the air pump (on a system engineered to include an air pump).

Also, on a personal experience note:
My son and I just finished a project where we used aftermarket eliminator pullies.
One eliminator was a Ford part, the other was an aftermarket brand I don't remember this moment. They both were horrible quality. The cheap plastic pulleys wobble and squeak from the very first use. I only found out after we bought the overpriced junk that you can use numerous belt routes and lengths to accomplish any pulley elimination.

I highly recommend just googling different belt routes and lengths to accomplish your goals, rather than buying eliminators.


Edit:
If you can't find a route and belt length that suits you for whatever reason, get a taylor's measuring tape and figure out your own custom route.
So long as the ribbed side of the belt is touching ribbed pulleys and the flat side of the belt is touching smooth pulleys, everything will rotate properly. You cannot screw up a serpentine belt unless you screw up smooth side vs ribbed side.

 

I drove my truck for quite some time with NO air pump and the factory exhaust intact (cats included). Not trying to argue, just sayin'...... Plugged the air tube coming up to the back of the engine, and ran just fine.

 

I got a 93 302 with no smog pump and not running the bypass pulley.
I using a cheap value craft belt from Auto Zone and it been 10,000 miles.
It only came off once last winter when it was very cold and wet out. It happen when I started the truck up. Must of frozen to one of the pulleys.

I heard the 5.8 you do not need the bypass pulley because the engine is wider and should not throw the belt.

 

You can save yourself some money and just gut the air pump. Thats what I did. I re-lubricated the bearings at the same time and welded the ports shut. It's basically just an idler pully now.
