Thanks ,actually I got the recommendation of MadVapes and i found some and ordered on VaporKings.In their descriptions they list if it will fit the 808''s as well .
Actually not all listed as 510 or 901's will fit ,that was my problem ...i use some carts that are slimmer at the bottom ( and
tanks too ) and alot of drip tips are too wide .The ones listed on VaporKings did indeed fit
I was just not going to pay my hardware vendor 5.95
Maybe these two vendors can help someone else too
