vacuum connector LZN100390L found at home depot
Sorry if in wrong area we found a solution for problem we had and thought we would share.
The "red" tab to release the larger "1/2" OD diameter vacuum hose broke. We called the dealer and were told the part meaning the red tab and the housing were not avail. any longer. He told us we had to buy a new valve cover. He did give us a part number to look up. It is INCORRECT
LZN100390L from the dealer this part number IS WRONG.
While on our search we saw these numbers also, all incorrect for sizing.
LZN100220 9mm (black top) NOT CORRECT FOR LARGER HOSE
LZN100220L 9mm (red top) NOT CORRECT FOR LARGER HOSE
LYC100510 and LYC100510L NOT CORRECT FOR LARGER HOSE
So, basically we pulled the red part our vacuumed all debris from inside where the little tabs broke off.
We found the correct part at home depot. We bought the part and simply "pulled" hard on the inner guts to remove the part we actually needed and inserted it into the vehicle.
The reason we are sharing this is the HOME DEPOT part cost a little over $4 and it was part number SKU 677596 or PL-3036, any of the half inch OD white plastic adaptors will work.
