I put long tube headers on my 87 bronco and got rid of the egr and most of the un used vacuum. Which also includes the smog pump. Can I leave it with the belt on it or do I need to bypass it?

You can leave it with the belt on. Does it still have the intake filtered or baffled?
With the intake hose removed they tend to suck in a bunch of dirt and then lock up. So leaving the pump in place is a short term solution.
Start looking for a shorter belt.

Yo Brent,
Remove pump and install shorter belt.
I don't have a specific size for you 87, so;
Removal, Belt in an 88 5.0; "...I tried an 89.5" first, 2 inches shorter than stock and it was too long. So I went back hoping for something about 88 or so and all they had was a 87.5. It was a bit short and a royal pita to put on but it is running fine. A lil tight but it should hold till I get an 88.2 which they can order..."

"... I have a 351, so i know mine is a little different. but my stock belt was 93.5 inches. when i took off the smog pump, i needed a belt 2 inches shorter. 91.5. thats the stock sized belt for a 90 bronco with a 302. so says the autparts store. if yours is like mine, and you need to lose two inches, try a belt 2 inchs smaller than stock. all my accesorys are placed like in the diagrame fireguy just posted. i also beleive there was a thread about this not to long ago, and people were listing part numbers..."

So the intake hose will run from the smog pump to where? I removed the egr, plugged off one port in the back of the block and capped off another and removed the pipes. Was it one of those?
