Looking for a filter.

[Z51JEFF]

Im looking for the small filter for the secondary solenoid.Short rant.I had the plenum off my car to clean up a few things,install the TB bypass.I noticed the vacuum pump wouldn't hold vacuum for more than 4 seconds so I track it down to the solenoid.I had a new one so I installed it,problem gone but the new part had a nipple for a filter while the old part had a small,square filter.I made a filter for the new part and put everything back together.I pull up my ZR-1 parts diagram and see the new part had a small slip on filter so I get the part number and head down to the dealer to get the part while its still out there.Give the parts guy the part number,order the part.Part comes in and its the square filter for the old design.$8.00 for a piece of foam that was 1/32 of an inch thick that was 1/4 by 3/4.No return policy on special order parts but I gave it a shot anyway,its the wrong part,parts guy said he ordered the part based on the number givin by me,Ya got me.Then I ask the guy to pull up the part in his system based on the part number givin by me,diagram shows the same part in my parts list,the slip on filter I ordered.Now Im gettin kinda pissed,the part in front of me is not the part I ordered so now I insist the guy give me a refund,says the best he could do was give me a deal on something else.I tell the guy to give a 100% or nothing at all,got a refund.Long rant but got my blood goin.So,now Id like to find the correct filter.
