smog pump

I have a 87 f150 with a 5.8l in it 2wd. Can you remove the smog pump off of the truck? If so is there a lot to it? The truck also idles fast what might be the cause of that ?

the smog pump can be removed, easy maybe.

You will need a shorter belt, i believe 96", or a idler bracket from Ford Racing

You will need to cut off and weld up the air tubes that go into the exhaust

I believe you will need to do something, can't remember what, for the diverter valves, otherwise you check engine light will be on constantly

Back to the high idle, it's pretty common for the intake gaskets ot leak on the back of the engine

I have a 93 5.8 and was going to do the same thing. I was told all I needed to do was remove, get the shorter belt and swap tensioner with one that flexes the opposite way. Is that right?

same tensioner, but it wouldn't hurt to get a little bit bigger pulley for better tension. I did it.
fordfuelinjection.com sells the resistors to make the check engine lights go away.
