D II Secondary air pump and charcoal canister filter
Today I pulled my secondary air pump to replace the rubber studs which had decayed beyond usefulness. While it was out I inspected the unit and the filter. The rivets on some connections had popped, and the filter was crumbling with age. First I took the pump down to my local ACE, and found some 1.5” #4 flat head screws, star washers, and nuts. The screws fit perfectly into the river shafts which I left in place for structural integrity. I went to my local small engine repair shop and purchased a Honda part #17211-889-000 air filter, about $7. This filter is made of the same material as the secondary air pump filter. So my wife made a pattern of the old filter, and cut me a new one from the Honda filter, and I installed it. Then it was time for the charcoal canister filter. I had taken the charcoal canister filter to the small engine shop as well, and they matched it with a lawn mower filter (lol)! I put that in the canister, and covered it with a circle of the remaining pump filter material, snapped the lid back on. Reinstalled everything, and even discovered a small but elusive coolant leak due to a loose heater hose clamp. Tightened that up, ran the engine up to temp, and voila no more leak and no check engine lights. Took the Disco for a 10 mile ride after a restart, and everything is super!
i posted this so anyone with secondary air with a bad filter, and coming apart could fix theirs without buying a new one. The same goes for the charcoal canister! Why buy a new one for $100 when you can fix it for $7? Be sure to check your pump, those rivets are junk!
Secondary Air Pump repaired with 1.5” #4 flat head screws, star washers, and nuts. Screws fit into rivet sleeves, so no need to remove the sleeves.

Here is another post from Geo about the SAI filter to help others out...
SAI rubber mounts and filter
Thanks Frtpilot for the tip about the charcoal canister. I've been meaning to open mine up and see if the insides can be easily replaced.
