Hi,

My 92 F150 4x4 351w doesnt have the Smog Pump hooked up and is missing the hoses/tubes & valves from the pump and needed to know how to fix this mess. I want the truck to run properly and need to know what to get. Any help much appreciated.

 

The motor should run fine without the smog plumbing unless you need a functional system for emissions tests of course. If the system is removed you just can't have anything that attaches to the exhaust upstream of the O2 sensor left open to the atmosphere, so if for example the crossover tube connecting ports on the back of the heads is still there is must be removed and the holes in the heads plugged.

 

ok, so if I want it all removed instead, just keep the EGR hooked up and the air sensors next to the coil hooked up?
