Hey guys. So here is my situation. I have long tube headers with true dual exhaust on my '91 4x4 5.0. It has been off of the road for a year or two due to my time in the military. I want to get it back on the road but right now with the exhaust setup the emissions are not connected and obviously the engine just dumps fuel. Is there a way to reconnect emissions and smog pump with the current setup or do I have to do a smog pump delete? If I do the second option is there a way to get the computer to regulate the fuel being used? Any help is appreciated, thanks everyone!!

 

The smog pump is just an air pump that pumps fresh air into the exhaust system. One of the valves will direct it through the heads and the other valve will direct it to the cats. The valves are at the back of the motor and the solenoids that run them are beside you coil. Deleting the (smog pump) fresh air system from the exhaust is not going to help pass an e-test.
The only way you'll get past emissions testing is to have catalytic convertors on there. They convert the carbon monoxide the engine is pumping out into carbon dioxide.
If you don't have any, you could maybe have a set of high flow cats installed that shouldn't restrict anything much.
It's possible that you could get away with not using the air line down to the cats and still get a passable reading, but it depends where you take it for testing. Some places are real sticklers for having all the original emissions equipment in place and functioning because technically they're supposed to be.
